How the Biology exam is scored
Each part counts for a fixed share of the composite. Raw points become a share of that part, then the shares add up to 100.
| Part | Length or points | Share of the score |
|---|---|---|
| Multiple choice | 60 questions, 90 minutes | 50% |
| Interpreting and Evaluating Experimental Results | 9 points | 13.2% |
| Interpreting and Evaluating Experimental Results with Graphing | 9 points | 13.2% |
| Scientific Investigation | 4 points | 5.9% |
| Conceptual Analysis | 4 points | 5.9% |
| Analysis of a Model or Visual Representation | 4 points | 5.9% |
| Data Analysis | 4 points | 5.9% |
Where the 1–5 estimate comes from
College Board doesn't publish the composite score needed for each AP score, and the cutoffs shift a few points every year. The estimate uses the cutoffs from College Board's 2013 released AP Biology exam, converted to a share of the total so they fit today's section weights. The exam's format has changed since then, so the cutoffs are a rough guide. Within 3 points of a cutoff, the calculator shows both scores.
