Algebra II – Midterm Review Packet
• GET ORGANIZED. Successful studying begins with being organized. Bring this packet with you to
class every day. Gather up all of your old quiz and test reviews as you might find them helpful. 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 graphs that you will want to put on your notecard.
• NOTECARD: I will provide you with a 5” x 8” notecard. You are allowed to include any information
on this notecard (front and back) that you think will be helpful for the exam. This will be turned in with
your exam. No points are awarded for making a note card – it is a helpful study tool! Your notecard
must be in your own writing.
• GRADE FOR PACKET: 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. YOU MUST
SHOW WORK.
✓ Correctness. I will check random problems to make sure they are correct, or that you made
corrections as needed.
• 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.
