It says updated 2017 but it should be the same for this year. I recommend any of the TI-84. If you choose to buy another one you are responsible for learning how to use it. I do have the TI-84 plus CE calculators to check out to you if you do not wish to purchase one.
In case you want to get a jump start on the first book assignment due Friday August 17 and you were not able to check out the textbook last year. Please see more detailed instructions on the summer packet
Here is the AP Calculus summer packet given at the end of the last school year. Please read over first page carefully. The summer assignment is due on Wednesday August 15, the third day of school but first regular class day.
