AP® Calculus AB Beta

Score calculator

Enter your multiple-choice and free-response results to get an estimated score from 1 to 5.

How the estimate works

Use the questions you got right and the points on each free-response question from a practice exam, or from a released one you scored with its rubric.

The exam has two sections worth half the score each: 42 multiple-choice questions (29 without a calculator, 13 with one), and 6 free-response questions worth 9 points each, 54 in all. So the calculator turns each section into a score out of 50 and adds them:

composite = 50 × (multiple-choice right ÷ 42) + 50 × (free-response points ÷ 54)

A composite of 66 or more is shown as a 5, 49 or more as a 4, 40 or more as a 3, 23 or more as a 2, and anything lower as a 1. There is no penalty for a wrong multiple-choice answer, so a blank and a wrong answer count the same.

These cut-offs are estimates, not official. The College Board sets the real cut-offs after each exam, from how that year's students did, and has published none for the current calculus exam. We chose ours so that, with the average free-response scores the College Board published for 2024 and 2025 (about 43% and 44% of the points), they give about the share of 5s (about 20%), 4s or better (about 49%), 3s or better (about 64%) and 2s or better (about 87%) reported for 2024 to 2026. How the 42-question multiple-choice section will be scaled in 2027 is not published either. Treat a result within about 5 points of a cut-off as either score, and use the estimate to see which section has the most room to grow.
