Find the Right Calculator
Students are expected to bring a graphing calculator to the AP Statistics
Exam and to the AP Calculus Exam. These calculators should have
specific computational capabilities. The College Board has prepared a
list of calculators that have all of the capabilities needed for
both exams.
AP Calculator Review
We found many of the APapproved calculators at Amazon.com,
and evaluated each on the following criteria.

Price: The price of a new or used calculator, as of
October 18, 2018.

User rating: From 1 (unacceptable) to 5 (excellent).
Evaluation findings are summarized below.
We only reported results for calculators that received reasonably acceptable ratings from students (i.e.,
calculators that received a satisfaction rating of at least 3.5 on a 5point scale).
Prices are current, as of October 18, 2018.
Recommendations
The best calculator for you depends on your personal needs. Here are some things
to consider.
 Cost. If you want a new calculator at a low price, choose the FX9750GII. If you want a used calculator at a low price, choose the FX9750GPLUS.
 User satisfaction. The highest rated calculator was the FBA_84PLCE/TBL/1L1/W, with a satisfaction rating of 4.8.
 Peace of mind. If you are looking for a calculator with a favorable satisfaction score based on ratings from a large number of users, consider the FX9860GII or the N3CAS/CLM/2L1. Both calculators received a satisfaction score of 4.6, based on ratings from at least 100 users.
One More Thing . . .
It is important for each student to bring an APapproved graphing calculator
to the exam. Here's why.

The test developers assume that students will have an
approved calculator. Students without a calculator will be at a disadvantage.

Nongraphing scientific calculators, portable computers, and devices with
QWERTY keyboards (e.g., TI92 plus, TIVoyage 200) are not permitted. Proctors
will check calculators before the exam.
