Geometry – Semester Exam Review
GET ORGANIZED. Successful studying begins with being organized. Bring this packet with you to class every day.
DO NOT FALL BEHIND. Do the problems that are assigned every night and come to class prepared to ask
about the things you could not do.
GET SERIOUS. The grade you earn on this exam is worth 20% of your semester grade.
MAKE NOTES AS YOU WORK. As you do these problems, you will come across formulas, definitions, problems, and diagrams that you will want to put on your notecard.
NOTECARD: Your notecard must be in your own writing. You may put on it anything you think will help
you on the exam. You may use the front and back. You will turn it in with your exam. You may also use your chart from Chapter 6.
There is nothing on the exam that you have not studied this year.
You will turn in your review packet on the day that you take your midterm.
This packet is worth a 1-weight quiz grade. This grade is based on:
Completion. I will check each day to make sure that day’s work is done. Correctness. I will check random problems to make sure they are correct, or that you made
corrections as needed. Participation. I will keep track of people who ask questions, answer questions or put problems
on the board. Everyone needs to participate at least three times.
