Understanding AP Approved Calculators: The Complete Guide
Success on Advanced Placement (AP) exams doesn't just depend on your knowledge—it depends on having the right tools. The College Board maintains a strict policy regarding which calculators are permitted in the testing room. Using an unapproved device can lead to score cancellation.
Which AP Exams Allow Calculators?
Not every AP exam requires or allows a calculator. They are primarily permitted for math and science-based subjects:
- AP Calculus AB/BC: Graphing calculator required for Part B of Section I and Part A of Section II.
- AP Statistics: Graphing calculator with statistical capabilities required for the entire exam.
- AP Physics (1, 2, C): Scientific or graphing calculator allowed for the entire exam.
- AP Chemistry: Scientific or graphing calculator allowed for the entire exam.
- AP Biology: Scientific or graphing calculator allowed for the entire exam.
Graphing vs. Scientific Calculators
While scientific calculators (like the TI-30XS) are allowed for most science exams, AP Calculus and AP Statistics specifically require graphing calculators. These devices must be able to:
- Plot the graph of a function within an arbitrary viewing window.
- Find the zeros of functions (solve equations numerically).
- Numerically calculate the derivative of a function.
- Numerically calculate the definite integral of a function.
Popular Approved Models
The following models are among the most commonly used and are fully approved by the College Board:
- Texas Instruments: TI-84 Plus, TI-84 Plus CE, TI-Nspire CX II (and CAS versions).
- Casio: FX-9750GIII, FX-CG50 PRIZM.
- HP: HP Prime, HP 48-50 series.
Prohibited Features
Even if a calculator is a "graphing" model, it may be banned if it includes certain features. You may NOT use:
- Devices with QWERTY keyboards (like the TI-92).
- Devices that can access the internet or have wireless/Bluetooth capabilities.
- Devices that require a power cord or make noise.
- Calculators built into phones, smartwatches, or tablets.
Exam Day Tips
1. Check Batteries: If using a TI-84 Plus CE, ensure it is fully charged the night before. If using AAA batteries, bring a spare set.
2. Clear Memory: While some proctors require clearing RAM, the College Board generally allows stored programs as long as they don't violate exam integrity. Check with your specific AP Coordinator.
3. Familiarity: Don't buy a new calculator the week of the exam. You should be able to perform regressions, find intersections, and calculate integrals quickly without looking for buttons.
Calculation Example for AP Physics
Suppose you are solving a kinematics problem where an object's height is given by h(t) = -4.9t² + 20t + 5. To find when the object hits the ground (h=0), you would use the Quadratic Solver on your approved calculator. By inputting a = -4.9, b = 20, and c = 5, you quickly find the positive root for time t, saving valuable minutes on the free-response section.
