∫ AP Calculus AB Calculator
The AP Calculus AB Score Calculator accurately estimates your AP exam score (1–5) based on the official weighting of the College Board. By entering your raw scores from the Multiple Choice and Free Response sections, this tool calculates your composite score and predicts your final AP grade.
Example: Scoring 28/45 on MCQs and 32/54 on FRQs typically results in a composite score in the AP 4 range.

How AP Calculus AB Scores Are Calculated
The AP Calculus AB exam score is derived from a Composite Score. Unlike simple percentage grading, the College Board applies specific weights to balance the two sections of the exam.
AP Calculus AB Exam Format
| Section | Time | Questions | Raw Pts | Weight |
|---|---|---|---|---|
| I. Multiple Choice | 1hr 45min | 45 | 45 | 50% |
| II. Free Response | 1hr 30min | 6 | 54 | 50% |
| Total | 3hr 15min | 51 | -- | 100% |
Scoring Formula
To ensure both sections count equally (50% each), the Multiple Choice raw score is multiplied by 1.2.
Max Possible Score: (45 × 1.2) + 54 = 108 Points.

These cutoffs are based on historical data. Exact curves vary slightly by year.
| Composite Range | AP Score | Result |
|---|---|---|
| 68 – 108 | 5 | Extremely Well Qualified |
| 53 – 67 | 4 | Well Qualified |
| 41 – 52 | 3 | Qualified |
| 30 – 40 | 2 | Possibly Qualified |
| 0 – 29 | 1 | No Recommendation |
Calculator Use Rules (Important)
Knowing when to use your calculator is key to scoring high.
- Part A (MC): 30 questions. No Calculator.
- Part B (MC): 15 questions. Calculator Required.
- Part A (FRQ): 2 questions. Calculator Required.
- Part B (FRQ): 4 questions. No Calculator.
Allowed Calculators: TI-84 Plus, TI-Nspire (non-CAS), Casio fx-9860, and similar graphing models. Note: Calculators with QWERTY keyboards (TI-92) are generally banned.
Tips to Improve Your Score
- Master the "Big Three": Limits, Derivatives, and Integrals are the core. If you are weak on derivatives, the Chain Rule will haunt you in the FRQs.
- Show Your Work (FRQ): Even if the final answer is wrong, setting up the integral or derivative correctly earns you partial credit.
- Practice Timing: The non-calculator MC section is fast-paced. Practice doing mental math for derivatives to save time.
