AP Biology score calculator

Your raw section scores are combined using College Board's official weights — Multiple choice (50%), Free response (50%) — into a composite, which is converted to the 1–5 scale. This calculator uses those exact weights.

Roughly 72% of the total composite, based on released exams — and about 57% for a 4 and 43% for a 3. College Board adjusts the real cutoffs each year, so treat these as estimates.

The section weights are official; the score cutoffs are estimates compiled from released exams and public scoring data. Weights are College Board's official figures for the May 2026 exam; cutoffs are estimates compiled from released exams and public scoring data. Real cutoffs shift a few points year to year, so a result near a boundary could land on either side.

Active recall on the exam's factual base. Cram turns your AP Biology notes into flashcards with AI and schedules them with spaced repetition, so the content side of the exam is locked in before test day.
