Geometry – Semester Exam Review
GET ORGANIZED. Successful studying begins with being organized. Bring this packet with you to class every day. Go through your folders and find all of the quiz and test reviews that we have been doing all semester. Use them to help you with each chapter.
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.
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.
