AP Biology Score Calculator

Based on publicly released past curves, a 5 has typically required a composite around 60% of available points — for example, about 36 of 60 mcq plus 20 of 34 free-response points. The exact 2026 cutoff will be set by the College Board's equating process after the exam.

Not in the classroom sense — your score never depends on how other students perform that year. Instead, the College Board uses equating to adjust raw-score cutoffs so a given AP score means the same thing across years. In practice it behaves like a conversion table that shifts a few points from year to year.

The current format is 60 multiple-choice questions (50%) and six free-response questions (50%): two long and four short. Section I gives you 90 minutes for 60 multiple-choice questions (50% of your score). Section II gives you 90 minutes for six free-response questions: two long questions built around experimental design and data analysis, and four short questions worth four points each.

Released curves have allowed a 5 at composites near 60% — but the grading is correspondingly strict. FRQ points are earned only when you perform the exact reasoning the verb asks for (justify, predict, explain), so the generous-looking cutoff and the demanding rubrics roughly cancel out.

The College Board typically releases AP scores in early-to-mid July. For the May 2026 exams, expect results in July 2026 — the exact date is announced on the College Board website closer to release.

No. Only correct answers count toward your multiple-choice score, so you should answer every question, even when you are making an educated guess.

It is an estimate. The calculator weights each section exactly the way the exam does and uses conservative cutoffs from publicly released past curves, but the College Board re-equates every exam year, so the real boundaries move a few points. Treat the output as a target-setting tool, not a promise.
