AP Bio Score Calculator
Enter raw multiple-choice and free-response scores from your AP Biology practice exam. Adjust max points and weights if your scoring guide differs. The calculator returns the weighted composite and an estimated AP score from 1 to 5.

Composite ≈ 68% · score 4

Composite ≈ 82% · score 5
MC 30/60 · FR 28/60
Composite ≈ 48% · score 2
How it works
Each section converts to a percentage (raw / max × 100), then combines with the weights you provide into a composite percentage. The composite maps to an AP score using estimated bands.
Composite · Σ (section% × weight) / Σ weight
AP score bands · 5 ≥ 70%, 4 ≥ 60%, 3 ≥ 50%, 2 ≥ 40%, 1 below

Frequently asked questions
AP Biology has 60 multiple-choice questions and six free-response questions. The two sections are weighted roughly 50/50, summed into a composite percentage, and mapped to a 1 to 5 AP score using cut points set each year by the College Board.
No. Earlier versions of the exam included a small number of grid-in numeric responses, but those were removed; current AP Bio is straight multiple choice in Section I and free response in Section II. If you are studying with an older practice exam that still has grid-ins, fold them into the multiple-choice raw score.
The free-response section is two long FRQs at 8 to 10 points each and four short FRQs at 4 points each, for 60 total points in current scoring. The calculator uses 60 as the default; adjust if your practice exam differs.
The College Board sets cut scores each year after equating. Published examiner statistics suggest typical bands around 70% for a 5, 60% for a 4, 50% for a 3, and 40% for a 2 on the composite percentage scale. Actual cut scores vary.
