SEMESTER REVIEW The exam does not go in order from Unit 1 to Unit 6 material, but rather random topics throughout. The level of difficulty also varies question to question. Don't get stuck on a hard question!!! Try them all and come back to the tough ones. We borrowed this review from a teacher online but can't remember who. Sorry, a big shout out to whoever made this review, it is solid. You will NOT be allowed to use the formula sheet on the exam. Bummer.
