3. Perform routine laboratory measurements including mass, volume, and temperature, and record them

with proper precision and units; distinguish between measured quantities (raw data) and calculated

quantities.

V. Academic Integrity and Student Conduct:

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton’s Code of Academic Conduct. This code prohibits:

cheating,

plagiarism (turning in work not written by you, or lacking proper citation),

falsification and fabrication (lying or distorting the truth),

helping others to cheat,

unauthorized changes on official documents,

pretending to be someone else or having someone else pretend to be you,

making or accepting bribes, special favors, or threats, and

any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton’s policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.

Please review the Code of Academic Conduct and the Code of Student Conduct, both located online at www.oakton.edu/studentlife/student-handbook.pdf.

Additional Instructor Comments: The Student Handbook (link above) includes procedures for how “irregularities” are handled, generally. Note that the following specific actions violate the Code of Academic Conduct:

1. Writing word-for-word or step-for-step (or nearly so) a homework or lab problem solution that is:

found on someone else’s paper (even if you “worked together”, see below),

generated by any other person (including a tutor!),

found in a PS answer key written by me (You should not copy my work step-by-step or word for word even in blue as a “correction”; you should paraphrase in your own words “reasoning” problems/corrections (in blue), and you should only copy initial setups (in blue) in cases where you need help getting started [but then do calculations/subsequent steps on your own in pencil or black ink without looking at key, and then check answer with the key at the end, as usual.)

Explanation: I want you to get help if you need it. However, my definition of “help” is: “aid which helps a student understand how to reason through a problem or calculation so that s/he can generate a complete solution to it on his/her own.” “Getting help” is not the same as “getting an answer”. If you cannot do the problem on your own after “getting help”, then you did not completely understand the problem and you should only hand in whatever you can that is your own. This includes lab

work!

For this class, “working together” on homework or lab reports means that discussion should occur to help each person understand each problem, but that after “working together”, each person should rework the problem (or re-answer the question) on his/her own paper without consulting anyone else’s work (or a scratch sheet that you’ve just generated the solution on). You MUST be honest with yourselves! If you can’t do the work on your own, you should not expect to be able to do the problems on the exam. NOTE: This also means that every calculated result found on each person’s paper should have been physically calculated by that person—no “jointly” obtained values. [Note: This is beneficial to students because if one person makes an entry error on the calculator, that error should be “caught” upon final checking (see below). Conversely, if both papers contain the same unexplainable error, it will be assumed that only one person actually physically made the calculation, which is an integrity violation.]

2. Taking possession of another person’s written work (even temporarily) to incorporate information in it into your own paper (even if you worked together!).

If you wish to check your final answers with someone else’s, it must be with their permission and it must be done in the presence of that person. You may not use their paper for anything more. If a difference is discovered, you may rework the calculation/problem again, possibly after verbal consultation, but ultimately on your own, without the paper. If you do not understand a calculation after consulting/discussing, you should not include that calculation (or result) on your paper. What if it isn’t correct? (ask me for help!) If you are asked for help from someone and are unsure about whether or not you can “help” in an appropriate manner, please politely decline, citing your concern about academic integrity. Certainly never give away your paper. Whenever in doubt, ask me.

ENFORCEMENT: My assumption is that no two answers on any students’ papers (or on a student’s paper and my answer key) should look word-for-word or step-for-step identical (or nearly so) unless at least one student has not handed in work that is his/her own. If I see any occurrence of this during the course of grading a problem set or lab report, I will treat it as an “irregularity”. A short summary of what will happen is (see Handbook for more details):

1) I will stop grading the paper, cross out any grade on any other paper with any nearly identical work that may have already been graded, and write “please see me” (and the current date) at the top.

2) I will make copies of the papers, and give back the originals in the next class period.

3) If you receive such a paper, you must schedule an appointment with me within one week to discuss. For a first occurrence, typically a “learning opportunity” is warranted; beyond that, (only) other options apply (see Code of Academic Conduct at www.oakton.edu/studentlife/student-handbook.pdf).

VII. Methods of Instruction:

Classes will include interactive lecture (in which I will often ask and/or answer questions of/from the class), using a mix of boardwork, PowerPoint, document camera, web exercises, or demonstrations. Discussions, worksheets, individual and/or group problem solving sessions, videos, and molecular models may also be used. Laboratory activities will involve hands-on explorations with subsequent analyses. Some group work may be done in lab.

VIII. Course Practices Required:

A. General. Students are expected to read completely and carefully any reading material associated with that week’s laboratory experiment before entering the lab (see “Laboratory Work” in Section X below). Exams and laboratory experiments require college level reading and writing skills. Communication skills are required to facilitate classroom discussions and question-asking. Laboratory/Safety practices information will be handed out and discussed during the first laboratory session.

B. Calculators. Students should bring a basic scientific calculator (TI-30Xa, TI-30X, and TI-36X are sufficient) to every class and lab. During exams, all students may be required to use calculators (similar to TI-30 level) provided by the chemistry department rather than their personal ones.

C. Showing (and legibility of) your work. Unless stated otherwise, work/reasoning must be shown and legible to earn credit. You can earn most points on a calculational problem if you set it up correctly but make a careless arithmetic error, but will receive ZERO points for a “coincidentally” correct (or unsupported) answer. This applies to non-numerical problems also (logic/reasoning needed). **Although work/reasoning is not mandated in the Mastering program, it is strongly encouraged for


5

students to write down setups and reasoning on separate paper to verify that they are getting the correct answer using valid reasoning, and not coincidentally. This will also help during review for exams.**

D. Exam make-up policy. If you have a foreseeable conflict (e.g., a religious observance, work-related trip, medical procedure, etc.) it is your responsibility to inform me in writing (email) at least two weeks before the scheduled exam to arrange for an appropriate accommodation. In the case of an unexpected emergency, you must notify me no more than 24 hours after by either phone (voicemail) or email. Notification does not guarantee a make-up. A make-up exam may be more difficult than the one given to the rest of the class, and must be taken as soon as possible after the date of the original exam (date determined by me; not checking your email or voicemail can cost points!). I may allow you to take it later, subject to a 10% per day penalty. All reports of illness must be accompanied by documentation for a make-up exam to be counted (although it can be provided after you take the exam).

E. Behavior in class/lab. Students shall refrain from any activity that may be a distraction to others in the class, and to treat others with respect. Students must clean up after themselves in the lab.

F. No eating or drinking in the classroom (except water and throat lozenges).

G. No usage of cell phones or headsets/earpieces in class, except when expressly allowed by me for academic purposes. If you have a cell phone on your person, it must either be OFF or in silent or vibrate mode. During exams, it must be OFF (it cannot be used as a calculator). If you need access to your phone for extenuating circumstances, please let me know. If a phone makes any noise during an exam, you may be penalized 4 pts per occurrence.

IX. Instructional Materials:

Textbook/Online Homework System: Chemistry: A Molecular Approach, 5/e, by Nivaldo Tro (ISBN: 978-0134874371) AND Pearson Education’s “Modified MasteringChemistry” (“Mastering”), an online software platform for online homework and other resources. **Students registered for this course will have the fees for access to an e-text of this book, as well as access to the Mastering platform, included on their Oakton bill.** As such, you will not need to purchase access separately—you will be able to access these from within my d2l shell by following registration procedures. Instructions for how to register for e-text/Mastering are provided in d2l. See additional eTextbook statement in Section XI.C below for further details & information on the option to purchase a loose-leaf copy of the text and the option to “opt out”.

Laboratory manual: “Chemistry 122 Lab Manual” (available from OCC Bookstore only; ~$60) [based on

Chemical Principles in the Laboratory, 8th edition, by Slowinski, Wolsey and Masterson.]

**NOTE**: Photocopies or handwritten report forms generally will not be accepted. Please see me if you feel an exception is warranted (e.g., if you have purchased the manual in a prior term). For some experiments, a custom-made report form will be provided to you at no cost.

Several laboratory periods will be devoted to experiments not found in the laboratory manual. Handouts describing these experiments will be provided to students at no cost.

Laboratory “notebook”: This can be any small (30-50 p. is fine), bound notebook (no “tablets”). The pages need not be pre-numbered, but if not, you must write them in yourself. No part of this notebook should be used for any other purpose (including class notes). See separate handout for additional notebook details.

3-ring binder: Required for course “portfolio” (see Section X.B).

Safety Goggles: Students are required to purchase their own Chemical Splash Goggles. These goggles must meet the following criteria: 1) Fit snuggly against the forehead and face, protecting against splashes; 2) Be impact resistant; ANSI rating of Z87 or higher; and 3) Include only indirect venting

Two varieties of such goggles compliant with the above criteria are available for purchase in the bookstore (cost range ~ $6-$12). Goggles obtained from another source are fine if they meet the above criteria. NOTE: Shop goggles, lab “visors”, and lab “glasses” do NOT meet the requirements above!

Optional Resource: ACS Study Guide for General Chemistry (ask instructor; can be borrowed)

X. Methods of Evaluating Student Progress:


6

A. Exams (total points: 800). There will be four midterm exams, possibly in parts (worth a total of 600 pts, but not of equal value [see schedule]), and one cumulative final exam (in two parts) worth 200 pts. Part of the final exam will be a standardized exam produced by the American Chemical Society (ACS).

B. Problem Sets (total points, after combining Mastering work with written work: 84 [not including portfolio points]).

There will be twelve problem sets during the term. Each set will typically have a part (or parts) done online

through the Mastering program, and a part submitted on paper (“Written”). These should be your primary

focus for practicing / learning the material and preparing for exams. Each set’s relative Mastering component

and written component may vary somewhat in terms of point value, but in the end, both parts will contribute

significantly to the total problem set grade. NOTE: Each point earned in a Mastering assignment is worth

the same as a point on a “Written” PS assignment, however, these points are not equivalent to a point on a

lab, exam, or portfolio. Rather, the fraction of total PS points (Mastering + Written) earned in the end will be

multiplied by 84 so that the sum total of points for all parts of the thirteen sets will be 84. For example, if the

final total number of PS points ends up being 371 (e.g., 182 from Written PS’s and 189 from Mastering), and

you earn 334, your final course points for PS’s will be 334/371 [= 90.0%] x 84 = 75.6 pt..

PS Expectations & Grading—Mastering: Detailed Grading Policies (e.g., # of allowed attempts, deductions for incorrect attempts & lateness, etc.) can be found in the Mastering program. Generally, students will have 5 attempts per answer (3% penalty per error) and can submit answers late with a 2% per day penalty (pro-rated, and only for items submitted late). Problems on exams will require reasoning and setups, even though the Mastering ones do not. Mastering is designed to help students and give feedback when I am not available. But I’m happy to help you on Mastering problems just like other course problems. Please ask if you suspect an error or quirk. 1% of Mastering points will be added back to account for program quirks.

Additional Mastering Comments: 1) Ability to print out Mastering problem sets or individual problems. Please note that the program provides an option to print out either an entire problem set or an individual problem. Look in the upper right corner of the dialog box when viewing the whole set or an individual problem. Ask if you cannot figure out how to do this. Printing out a problem may be useful for a variety of reasons such as: a) showing all of your setups and work so that if your answer is incorrect, you will know what you did to get that answer [easier for you to find errors in your work, to ask for help from me or a tutor, and helpful for studying for exams!], or b) if you wish to work on problems “offline”, either on your own or in the tutoring center or in my office during office hours. Obviously, if a problem has a video to watch or hints to access, you will lose that functionality in the printed version. 2) Hints clarification. Please realize that you do not lose any points for viewing a hint! So please don’t be afraid to view the hints! That said, you can incur a minor penalty (lose partial points) if you actually answer a question within a hint and you get it wrong. But the penalties here are minor, and one of the benefits of the program is to have the hints there to help you learn, so I really suggest using them, if needed!

PS Expectations & Grading—Written Parts: 1) To earn full credit, write problems in the order in which the problems appear on the PS sheet; see X.F.

2) Detailed answer keys will be posted for all written problem sets before sets are due, but you are absolutely not to copy answers from the key (See Section V). Rather, you must first attempt each problem on your own, using “normal” resources (includes me or a tutor!) without consulting the key at all. Use pencil (P) or black ink (Blk) for this and leave plenty of space above, below and in the margins. Then, preferably after each problem, access the key and make comments and/or corrections (details follow) using blue (B) ink. Do not erase original work! If an answer to a calculation is incorrect, you must identify the error in your original setup, correct it, and rework the problem (w/ B)—do not copy from the key, even in B! If reasoning is incorrect, line it out and write correct reasoning (in own words) (B) using the key for guidance (not copying). If answer is correct but you gain insight from the key, make a helpful comment to yourself. The idea is for you to get practice doing problems on your own plus immediate feedback and correction info while also differentiating between what work is yours (P/Blk) vs. mine (B). Note: The “complete” keys will generally contain more information than you will need in order to receive full credit. I expect you to be thorough, but not to replicate my key!!

3) Answer keys may contain errors! Since all setups are shown in the key, you should determine whether


7

an answer that does not match your own is actually correct or in error! Do not assume that you are incorrect just because a final answer does not match—doublecheck the work! It is crucial to your learning, and to your integrity, for you to submit only work that is your own (See Section V.) As such, if even one error from a key is found on a PS paper as if it is a student’s own work (i.e., in P/Blk, not B), a 30% deduction on the set will result. Please be responsible and have integrity! If you do not have enough time to complete work, or you don’t understand something, just do your best, “take the hit”, and/or write me a note about that on your paper—don’t take information from the key as your own. A subsequent occurrence will be considered an academic integrity irregularity (see Section V).

4) Uncorrected/unmarked problem sets will receive a maximum of 70%. I.e., the

“correction/annotation” action is part of the assignment and counts for points. Note: you will not be graded

on what you originally got right or wrong. If you have made all corrections/comments as noted above,

you will receive full points, even if you had to make a lot of them. The point is to reach understanding on

how to do every question and generate a document that will be helpful to you while studying.

5) A full grading rubric for written PS’s is as follows:

< 50% 50% 70% 80-90% Full Credit Most of set not

completed. OR

Half of set completed, but

little or no corrections were made, or work is

very brief throughout with

little or no work/reasoning

shown

Roughly half of set was completed

correctly. OR

Majority of set was completed, but

few/no corrections were made, or

answers are very brief throughout with little to no work/reasoning

shown.

All problems completed, but: (almost) no corrections and annotations were made OR

responses are extremely brief throughout with little to no

work/reasoning shown OR incorrect responses are marked as correct.

OR A majority of problems are

completed and corrected, but a substantial minority were either not completed, are not corrected, or are

“corrected” incompletely or incorrectly.

OR An error from the key appears in the set as a person’s own work, but there

is evidence that the majority of the rest of the set was done correctly.

Vast majority of problems are reasonably

attempted and corrected/

checkmarked/annotated in blue appropriately,

but some problems are either not completed,

are not corrected, or are “corrected” incompletely

or incorrectly. OR

Set is “completed”, but only some corrections and few annotations

were made or responses are brief throughout,

with weak reasoning or little work shown.

All problems reasonably attempted, on own, in the proper order (from

list on PS sheet), checked in blue if

correct, and corrected in blue if needed.

Reasoning is provided and/or work is shown

(setups) for all problems. Some

annotations/ comments appear in margins. Clear that key was

accessed and looked closely at as a means to

help deepen understanding of

material in problem set.

NOTE: If multiple errors from key appear in the set as a person’s own work, and/or

many solutions are extremely similar to the answer key (and written as a person’s own work), the paper will be marked “See me”

as per Section V (Academic Integrity)

C. Portfolio/3-ring binder (total pts: 16). At a minimum, the portfolio will contain four distinct (separated)

sections in a 3-ring binder with dividers, front/rear pockets and a hard spine: 1) Problem sets: file all PS handout sheets in strict sequential order w/ corresponding returned (graded) paper following each PS sheet, 2) Lab: file all lab handouts & returned lab work, 3) Lecture handouts: file any handouts other than PS sheets or lab-related handouts, in reasonable sequential order (by unit), and 4) Returned exams (exams will be returned to me at the end of the term). The course syllabus can be put, separately, in front, if desired. If a student decides to include other work (i.e., PowerPoint slides, outside info, etc.), it must be in additional (separated) labeled, orderly sections. Portfolios will be assessed during Exams 1 and 2 (2 pt each), Exam 3 (4 pts), and the final exam period (8 pts). NOTE: a portfolio that is missing many assignments may not earn full points. I.e., completeness and orderliness both contribute.

D. Laboratory work (total pts: 285). There will be a total of 14 experiments worth 20 pts each (not including

notebook, which is graded separately [see below]). Each will involve a prelab assignment (worth ~5 pts) and the lab work / report form (worth ~15 pts). The prelab assignment for each week (described on the schedule page in the syllabus!!) is due at the beginning of each lab period. It may be what I call a “prelab analysis” (details in separate handout) or a different type of prelab assignment. You must hand in your own report form with your own work (See Section V). NOTE: Setups for all calculations must be clearly shown, either on the report form or on separate attached paper. Otherwise, the report form may be returned ungraded, only to be graded after the paper is resubmitted with work shown/completed. A late penalty will be applied based on the resubmission date (See Section X.F) Never use another person’s data without instructor approval. All students must contribute substantially to collection of the data. The lowest lab score will be dropped. Lab notebooks can be inspected


8

unannounced during any lab or collected at the end of lab on any given day for grading (students can take a photo of pages needed for that week’s report form); total notebook points for the term is 25. Details for how to keep a lab notebook to earn full points will be provided in a separate handout. Its primary purpose (in this course) is for recording all raw data as they are acquired during lab, in ink, on a dated, titled page, with sufficient descriptors as well as units (see handout). Assumed information and unknown numbers should also be recorded. No post-lab work is to be included for points in the lab notebook, so it should be “complete” each lab day before you leave lab!

E. Responsibility Points (total points: 15). Start with all points. Lose points if you do not: attend requested

post-exam meeting, complete student info surveys/feedback forms, see me if you are struggling, respond to written requests from me, come to class on time or attend regularly, forget lock combo or goggles in lab (see Section X.F. below), etc.

F. INCENTIVIZATION OF RESPONSIBLE BEHAVIOR AND COMPLETION OF WORK PROMPTLY:

Deadlines in this course are provided to help with focus and incentive. I know students have busy lives, and I believe that without deadlines and consequences for not completing work, students are much less likely to complete it, and thus less likely to learn and succeed. There is a great deal of material and work this term, and if one gets behind, it is generally harder than it might seem to catch back up. With the understanding that sometimes “life happens”, I have made the consequences for submitting work late sufficiently minor that if work is a bit late a handful of times during the term, it is extremely unlikely to affect your final grade (so don’t stress over a late paper once in a while!). However, submitting work very late and regularly during the term not only will likely affect your course grade directly, but also your learning and thus exam performance. Also, to incentivize responsible and safe practices associated with the lab, failure to have goggles in lab or remember your lab drawer lock combination will result in a deduction.

XI. Other Course Information:

A. Comment on office hours. I strongly encourage you to see me early and often in the term, regardless of how minor any concern or question of yours might seem. You do not need to make an appointment—I will be in the designated room (see syllabus) or in a different room (with a note posted on the listed room’s door) during the posted office hours, unless I indicate otherwise via email.

B. How to approach “problem sets” in this course. Consider your goal to be not merely to complete them, but to use the problems and questions to think about and work with the course material. Feel free to email me if you have questions on any of the problems while you are working with them.

C. eTextbook: On the first day of the course you will have direct access to the eTextbook (i.e., the full electronic textbook) via our course web site. You are charged a DDA (Direct Digital Access) fee upon registration that includes access to the eTextbook. Because you've already paid for it via your tuition/fees bill, you should NOT purchase the textbook via other means. If you want to "opt-out" of the DDA program, or if you need more information, please contact [email protected].

Optional print version of the textbook: Your DDA access qualifies you to purchase a loose-leaf version of the textbook (NOTE: this is the entire Tro text, 5/e, the first half of which was used in CHM 121) at a discounted price, either directly from Pearson (~$40) or from the bookstore (~$52). To order from Pearson, click on the E-Text link within your Mastering course (make sure to access the course via d2l). Then, click on the link that reads, “buy an unbound version of your book . . .” For video instructions visit: https://screencast-o-matic.com/watch/cFlrqir7dm

D. Using OCC’s Many (Free!) Services. Many support services are available to all Oakton students, including free tutoring (from professional tutors) in nearly every subject (including math and chemistry), free ESL support, free academic/career/personal counseling, free computer/ web/software access, and more, Contact the Learning Center (635-1658, Rm 2400), Advising, Transitions, and Student Success (635-1700, Rm 1860), Wellness Center [Personal Counseling] (635-1885, Rm 1200), Career and Transfer Center (635-1735, Rm 2901 [access via enrollment center]), or the Office of Student Affairs (635-1739, Rm 2270) for more info. Room numbers given are for DP; call if you need RHC locations.

A complete listing of these and many other Resources for Oakton students will be posted in a Content Module entitled “Student Resources” in the course d2l shell!

E. Student Clubs! I strongly encourage you to consider exploring the many student clubs/organizations that Oakton has to offer. I’m confident that you can find at least one that will interest you, and although you may not initially feel like you have time to devote to it, once you give it a try, I think you’ll find that it helps you overall to not only clear your mind and allow you to “destress”, but also develop

personal relationships here at Oakton to provide support. Check out the following URL (also found in a module in d2l):

https://www.oakton.edu/studentlife/student_activities/clubs/index.php

F. If you have a documented learning, psychological, or physical disability you may be entitled to reasonable academic accommodations or services. To request accommodations or services, contact the Access and Disability Resource Center in the Learning Center (635-1759, Rm 2405). You can also click the “Requesting Services” link at http://www.oakton.edu/studentservices/disability_services/ for more information. All students are expected to fulfill essential course requirements. The College will not waive any essential skill or requirement of a course or degree program.

G. Any student who is unable, because of his or her religious beliefs, to attend classes or participate in any required exam, study, or work on a particular day shall be excused from that exam, study, or work requirement and shall be provided with an opportunity to make up any requirement that he or she may

have missed on that day, provided that he or she notifies the faculty member or instructor well in advance* of any anticipated absence or conflict between a scheduled class and the religious observance, and provided that the make-up exam, study, or work does not place an unreasonable burden upon the institution. *In my class, “well in advance” means “at least two weeks in advance”

H. Oakton Community College is committed to maintaining a campus environment emphasizing the dignity and worth of all members of the community, and complies with all federal and state Title IX requirements.

Resources and support for

• pregnancy-related and parenting accommodations; and

• victims of sexual misconduct

can be found at www.oakton.edu/title9

Resources and support for LGBTQ+ students can be found at www.oakton.edu/lgbtq

I. If you are pregnant or become pregnant during the semester, you have the option to meet with me to discuss reasonable accommodations that may be necessary. It may not be possible to grant accommodations after the fact, so it is better to prepare in advance for any possible scenarios.

J. Oakton has implemented an academic intervention program (StudentsFirst), and I am a participating faculty member. I am committed to helping you succeed in this course and at this college. I may, therefore, refer you to other individuals (e.g., your advisor) and/or services available to help you achieve academic success. Please understand that these referrals are intended to supplement, not replace, interactions you may have with me during office hours or in class. They are intended to provide a support network for your academic and personal success at the College. As such, please help us help you by responding promptly and appropriately to these referrals. If you have any questions at all about this, please ask! NOTE: Please do not react negatively if you receive an electronic referral! It will say something like “Your grade is at risk!”, designed to get your attention, and I cannot change that wording. This does not necessarily mean your grade is an “F”. Please do not be embarrassed! I (and others at Oakton) want to help and will not make you feel bad. Please don’t wait for “the next exam”.

K. Oakton Emergency Building Closures. When an Oakton building is closed due to an emergency (e.g., weather-related closings), that doesn't necessarily mean instruction stops. Students should check for communications from their instructor. This may take the form of D2L Announcements on your course home page, an announcement on another learning management system, or via email or text. If you don't receive something from your instructor, please contact them via email.

L. Electronic video and/or audio recording is not permitted during class unless the student obtains written permission from the instructor. In cases where recordings are allowed, such content is restricted to personal use only. Any distribution of such recordings is strictly prohibited. Personal use is defined as use by an individual student for the purpose of studying or completing course assignments.

For students who have been approved for audio and/or video recording of lectures and other classroom activities as a reasonable accommodation by Oakton’s Access Disabilities Resource Center (ADRC), applicable federal law requires instructors to permit those recordings. Such recordings are also limited to personal use. Any distribution of such recordings is strictly prohibited.

Violation of this policy will result in disciplinary action through the Code of Student Conduct.

M. The last day to withdraw and have a course dropped from your record is Feb 18*. The last day to withdraw with a “W” on your record is Mar 30*. You are responsible for making sure your OCC bill is paid on time. Note: I do not have any authority to drop you from this class at any time; students initiate their own drops in the first ~9 weeks; students still on a roster after that will get a grade (barring the approval of a written petition to be administratively withdrawn, which does not involve me [see: http://www.oakton.edu/admission/register/general_info/withdrawal_from_classes/ ])
