AP Biology — equal weight MC and FRQ
AP Bio Score Calculator
AP Biology splits the exam 50/50 between 60 multiple-choice questions and six free-response questions (two long at 9 points, four short at 4 points, max 34). Enter your practice raw scores to get a weighted composite and an unofficial 1–5 estimate.

How this AP Bio estimate is built
- Count multiple-choice correct answers out of 60 (50%).
- Score FRQs: two long responses up to 9 points each and four short up to 4 each (max 34, 50%).
- Composite = (MC ÷ 60) × 50 + (FRQ ÷ 34) × 50.
- Map the composite to 1–5 with the unofficial cutoffs listed in Sources.
AP Biology is a hybrid digital exam: MC in Bluebook, FRQ handwritten in a return booklet.
Good for practice
- Scoring a full practice exam after you total the FRQ rubric points
- Deciding whether to drill grid-in style MC sets or experimental FRQs next
- Explaining the 9-point long / 4-point short FRQ structure to a study group
- Tracking composite progress across several practice tests
Do not treat as an official score
- Forgetting the four short FRQs when totaling free-response points
- Using a 100-point FRQ scale from an old worksheet
- Assuming science curves match AP Lang cutoffs
- Reading the predicted 5 as a guarantee on the operational exam

Frequently asked questions
How many points is each AP Bio FRQ worth?
Two long questions are worth 9 points each; four short questions are worth 4 points each. That is 34 points before weighting.
Is the exam still 50% multiple choice?
Yes per College Board’s AP Biology exam overview.
Can I enter decimals for partial rubric credit?
Use whole points as your practice rubric awards them. If a teacher gives half points, round the way your classroom does before entering.
Does this include the grid-in questions?
Grid-ins, if present in your practice set, count toward the multiple-choice total out of 60.
