You are being asked to create your own AP CALCULUS Survival kit. For the survival kit you will need: Index cards Ring (so that you can put all of your flash cards together) Hole punch (to punch holes in your flash cards) Pen Color markers/pens/pencils Directions: First step: On the front of your index card you will write the left of the column. On the back you will write the right of the column. On the back side you will either draw an example or illustration with meaning to better understand the front of the flash card. Each flashcard should be numbered with the corresponding number. You will be graded on competition of all of the flash cards as well as how detailed your examples are. The last step is to create 5 flash cards of topics/concepts that aren t listed below that you feel would be useful information to know for your AP exam. Remember, you are being asked to rewrite the information below. DO NOT Print and cut the information onto a flash card.
