AP Biology Score Calculator (US Exam)

Both sections are worth half the exam, so each contributes 50 of the 100 composite points. Sixty multiple-choice questions face 34 raw free-response points — two long questions at 9 points and four short ones at 4. The composite is rounded before the cut score applies.

The score shown here is not an official AP result but a reconstruction of one: your own tally of correct multiple-choice answers and your own reading of the six free-response rubrics, run through the weighting the College Board publishes for this exam. Section I and Section II are each worth half, so the calculator scales 60 questions onto 50 points and 34 raw free-response points onto another 50. The default entries show what that does to the arithmetic: 45 correct questions give 45 ÷ 60 × 50 = 37.50, and 21 free-response points give 21 ÷ 34 × 50 = 30.88, a composite of 68.38. That total is rounded to 68 before anything else happens, and only the rounded figure meets the cut score — 62 or more is a 5, so this profile lands there with room to spare. Because 34 raw points and 60 questions carry the same 50, the free-response half is the denser currency: the most extreme test case, 14 correct questions beside a flawless free-response section, still makes 61.67, rounds to 62 and reaches a 5. The caveat is the ladder itself. The section weighting is published, but 62, 49, 37 and 26 are estimates — the College Board does not release current-year thresholds, and they move with the difficulty of the paper. A composite sitting on a boundary says less than it appears to.
