How your score is calculated

Multiple choice: right answers ÷ 42 × 50%

Free response: your points ÷ maximum points × that part's weight

Composite = the sum, as a percentage of the maximum. The composite then maps to a 1–5 score.

Tips for more points

  • Free-response rubrics give points for setup and reasoning, not just the final answer — show the equation before the number.
  • Answer every multiple-choice question: there's no penalty for guessing.
  • Practise with released free-response questions from AP Central and score yourself against the official scoring guidelines.

Questions

What percentage of students get a 5 on AP Calc AB?

In May 2026, 20% of students scored a 5 on AP Calculus AB, and 65% scored 3 or higher (College Board score distributions).

How many multiple-choice questions can I miss and still get a 5?

With about 70% of the free-response points, our estimated curve puts a 5 at roughly 25 of 42 multiple-choice questions right — so you could miss about 17. The real cutoff moves a little each year.

What do I need to pass AP Calc AB (score a 3)?

With about half the free-response points, you'd need around 15 of 42 multiple-choice questions right for a 3 on our estimated curve — roughly 36% of the section.

Are these the official cutoffs?

No. College Board sets the composite cutoffs for each score after the exam is graded and doesn't publish them. We use estimates based on released scoring worksheets and how generous each exam's score distribution is.

When do AP scores come out?

AP scores are released in early July in the College Board student account. Colleges you chose to send scores to receive them at the same time.
