COURSE POLICIES
1. The three long exams and the final exams are departmental and are taken on the scheduled date and time.
2. Exemption Rule: A student may be exempted from taking the final exam when all the following conditions are satisfied: (a) passed all long exams, (b) has an average long exam score of at least 70%, and (c) has an average of at least 70% in the quiz/probset grading criterion. The final grade will thus be computed as follows: 60% for the long exams, 25% for the average of the three long exams and 15% for quizzes and problem sets.
3. A student is allowed to take ONLY ONE make-up exam when he/she misses a long exam and has a valid reason for missing the exam. In the case of illness, bereavement, or official UP duty, a medical certificate, death certificate, or official endorsement, respectively, must be submitted as soon as possible. The makeup exam, which is comprehensive, is given at the end of the semester, after the final exam. In case of a second missed exam, a grade of zero will be given for that exam.
4. A grade of INC will be given to students who missed 2 out of 3 long exams OR the final exam, due to valid reasons, provided that the prefinal grade is passing; otherwise, a grade of 5.0 is given. The student must take the final exam in Physics 71 within one (1) academic year of incurring the INC; otherwise, the final grade will be computed with a score of zero for the missed exam.
5. A grade of 4.0 means a conditional pass. If a grade of 4.0 has been incurred, he/she will have to apply for a removal exam permit and take the removal exam within an academic year. The removal exam is a problem solving type exam covering the course objectives of the semester. The exam is composed of both conceptual and numerical questions. No partial points are given in each item. The passing score is 50% of the total score.
6. When removing grades of 4.0 or INC, the student must be enrolled during the term the removal/completion exam is taken. 7. The deadline for Dropping is on February 20, 2014 (Thursday) and for Leave Of Absence (LOA) is on March 7, 2014
(Friday). A student granted a LOA will only be given a grade of either DRP or 5.0. A grade of 5.0 is given if the LOA is granted after of the semester has lapsed and the student's class standing is failing; otherwise a grade of DRP is given.
8. University rules apply for attendance. A grade of 5.0 will automatically be given to students who missed 10 class meetings (excused or unexcused) excluding the recitation classes.
9. Any form of cheating in examinations or any act of dishonesty in relation to studies, such as plagiarism, shall be subject to disciplinary action.
10. The corridors, rooms, entry and exit points of the National Institute of Physics are under CCTV surveillance.
