How the AP Bio exam is scored
The 2027 AP Biology exam is on Monday, May 3, 2027 (Session 2, usually afternoon), and AP scores come out in July.[6][7] AP Biology is a hybrid exam: you answer the multiple-choice questions and read the free-response questions in Bluebook, then handwrite your free-response answers in a paper booklet. Each section is half of the score.[1] In hybrid exams you read everything in Bluebook but handwrite free-response answers in a paper booklet.[4]
| Part | Questions / points | Time | Share of score |
|---|---|---|---|
| Multiple choice | 60 questions | 1 h 30 min | 50% |
| Long free response | 2 questions, 9 points each (Q2 includes graphing) | 1 h 30 min for all six | 50% for all six |
| Short free response | 4 questions, 4 points each |
Section II has two long questions and four short ones. In the 2026 scoring guidelines the long questions are worth 9 points each, and the second one includes a graph. The four short questions are worth 4 points each, one of them on analyzing a model or visual representation, for 34 points in total.[5]

How this AP Bio score estimate works
No AP Bio chart has ever been released, so the 1–5 uses the average of nine other subjects’ charts. See where the cut points come from.
| AP score | At least |

| 5 | 70.1% |
| 4 | 58.1% |
| 3 | 46.6% |
| 2 | 34.6% |
Example
65% of the multiple choice plus about half the free-response points gives 59%: an estimated 4.
College Board does not post per-question weights for AP Biology or 2025 scoring statistics, so the calculator weights every free-response point equally. On that basis each point is worth about 1.5% of the exam, and a full 9-point long question is worth as much as about fifteen multiple-choice questions.
