Can You Use a Calculator on AP Calculus AB?

A guide and policy checker for the official College Board rules.

AP Calculus AB Calculator Policy Checker

Select your graphing calculator model from the list below to check if it’s generally permitted for the AP Calculus AB exam. This tool is a guide; always verify with the official College Board list before your exam.

What is the AP Calculus AB Calculator Policy?

The question “can you use a calculator on AP Calculus AB” is crucial for any student preparing for the exam. The simple answer is yes, but only on specific sections and only with an approved model. The College Board, which administers the AP exams, has a strict policy to ensure fairness and to test your mathematical reasoning, not just your ability to press buttons. Graphing calculators are required for certain parts of the exam because they have built-in capabilities to plot graphs, find zeros of functions, and numerically calculate derivatives and integrals. However, devices with features like a QWERTY keyboard, wireless communication (like Bluetooth or internet), or a stylus are strictly forbidden.

AP Calculus AB Exam Format and Calculator Use

Understanding the exam’s structure is key to knowing when you can use your calculator. The AP Calculus AB exam is 3 hours and 15 minutes long and is split into two main sections, each with a calculator and a no-calculator part.

Failing to follow the rules can result in your score being canceled, so knowing which calculator models are on the official approved list is essential.

AP Calculus AB Exam Section Breakdown

Section	Part	Question Type	Number of Questions	Time Allotted	Calculator Use
I	A	Multiple Choice	30	60 minutes	Not Permitted
I	B	Multiple Choice	15	45 minutes	Permitted
II	A	Free Response	2	30 minutes	Permitted
II	B	Free Response	4	60 minutes	Not Permitted

Practical Examples of Approved & Banned Calculators

Example 1: The Gold Standard (TI-84 Plus CE)

• Input: Texas Instruments TI-84 Plus CE
• Units: N/A (Device Compliance)
• Result: APPROVED. This model is one of the most common and fully compliant calculators for the exam. It has all the required graphing and calculus functions without any prohibited features.

Example 2: The Prohibited Device (A Smartphone)

• Input: A smartphone with a calculator app
• Units: N/A (Device Compliance)
• Result: BANNED. Smartphones have internet access, cameras, and communication capabilities, which are all explicitly forbidden by the College Board. Using a phone will lead to immediate disqualification.

Key Factors That Affect Calculator Approval

The College Board’s decision on whether to approve a calculator for the AP Calculus AB exam hinges on several key factors:

• Graphing Capability: The calculator must be able to graph functions. This is a non-negotiable requirement.
• No QWERTY Keyboard: Devices with a typewriter-style keyboard (QWERTY) are banned to prevent the storage of text notes.
• No Wireless Communication: Any device that can connect to the internet, Bluetooth, or other wireless networks is strictly prohibited.
• No Stylus or Pen-Input: Calculators operated with a stylus are generally not allowed.
• No Computer Algebra System (CAS): While some CAS calculators are permitted, the College Board is moving towards non-CAS models. It’s crucial to check your specific model. The TI-Nspire CX CAS is on the approved list, but it’s an exception rather than the rule.
• No External Peripherals: The calculator cannot be connected to any external device, including printers or extra memory cards.

Frequently Asked Questions (FAQ)

Can I use a scientific calculator on the AP Calculus AB exam?

No, a graphing calculator is required for the calculator-permitted sections. Scientific calculators lack the necessary graphing and calculus functionalities.

Do I need to clear my calculator’s memory before the exam?

No, the College Board states that calculator memories do not need to be cleared before or after the exam. However, storing test materials is strictly forbidden.

What happens if my calculator runs out of batteries?

You are allowed to bring up to two approved calculators. It is highly recommended to bring a backup and/or fresh batteries to avoid this issue.

Can I use a calculator with a Computer Algebra System (CAS)?

It depends. Some CAS calculators, like the TI-Nspire CX II CAS, are on the approved list. However, you should check the official College Board list for your specific model, as policies can change.

Is the TI-89 approved for the AP Calculus exam?

Yes, the TI-89 and TI-89 Titanium models are on the approved list for the AP Calculus exams.

Where can I find the official list of approved calculators?

The College Board maintains the official list on their AP Students website. You should always check the most current version of this AP calculator policy page before your test.

Are there parts of the exam where I absolutely cannot use a calculator?

Yes. Both the multiple-choice and free-response sections have a dedicated part where calculators are strictly prohibited. These questions are designed to test your analytical skills without technological aid.

Can I share a calculator with a friend during the exam?

No. Sharing calculators is strictly forbidden and can lead to score cancellation.
