You're within a few points of a cutoff, so a 3 or a 4 are both realistic. Cutoffs move from year to year.
How the Chemistry 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% |
| Long Free Response 1 | 10 points | 10.9% |
| Long Free Response 2 | 10 points | 10.9% |
| Long Free Response 3 | 10 points | 10.9% |
| Short Free Response 1 | 4 points | 4.3% |
| Short Free Response 2 | 4 points | 4.3% |
| Short Free Response 3 | 4 points | 4.3% |
| Short Free Response 4 | 4 points | 4.3% |
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 2002 released AP Chemistry 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.
