How does this calculator work?
Composite = MCQ raw (0–60) + FRQ raw (0–32) × 1.875, giving a score out of 120. Approximate AP score thresholds (2022–2024): 88+ → 5, 70+ → 4, 50+ → 3, 36+ → 2. Exact cutoffs change yearly and are set by College Board after each exam.
Formula
How this is calculated
The AP Biology exam has two sections of equal weight. Section I is 60 multiple-choice questions, each worth one raw point, contributing 50% of the composite. Section II is six free-response questions — two long FRQs worth 8 points each and four short FRQs worth 4 points each — totalling 32 raw points, also contributing 50%. To combine sections on the same scale, the MCQ raw score (already out of 60) is used directly, while the FRQ raw score is multiplied by 60 ÷ 32 ≈ 1.875, giving a composite out of 120.
College Board converts the composite to an AP score from 1 to 5 using cut scores determined after each exam to reflect a consistent standard of college-level achievement. The exact thresholds are not published in advance and shift slightly from year to year to account for exam difficulty variation. Based on publicly released scoring information from 2022–2024, approximate cut scores are: 88 for a 5, 70 for a 4, 50 for a 3, and 36 for a 2, all out of 120.
This calculator uses those approximate thresholds as a planning tool. Your actual College Board score may differ, particularly if cut scores shift due to exam difficulty adjustments. The FRQ raw score should reflect the sum of points awarded by the AP exam reader — long FRQ questions are graded on a 0–8 rubric and short FRQs on a 0–4 rubric.
Frequently asked questions
Section I: 60 multiple-choice questions (90 min, 50% of score). Section II: 6 free-response questions — 2 long (8 pts each) and 4 short (4 pts each) totalling 32 raw points (90 min, 50% of score).
Approximately 88 out of 120 in recent exam years, though cut scores change annually. A composite of 88+ corresponds to a 5 based on 2022–2024 released scoring information from College Board.
No. Since 2011 all AP exams use rights-only scoring: one point for each correct answer, zero for wrong or blank answers, and no guessing penalty.
