How the AP® Chemistry composite is calculated
Each section is converted to a percentage and weighted using the College Board's published exam weights:
| Section | Format | Weight |
|---|---|---|
| Multiple choice | 60 questions, 90 min | 50% |
| Long free response | 3 questions × 10 points | 32.6% |
| Short free response | 4 questions × 4 points | 17.4% |
The free-response section (50%) has 46 raw points: three long questions worth 10 each and four short questions worth 4 each. Every raw point counts the same.
The weighted composite (0–100) is compared with estimated score cutoffs:
| AP® score | Estimated composite |
|---|---|
| 5 | 70 and above |
| 4 | 56–69 |
| 3 | 42–55 |
| 2 | 30–41 |
| 1 | Below 30 |
These cutoffs are estimates based on past exams and score distributions. The College Board doesn't publish its raw-score conversion and adjusts it each year. If you're within 3 points of a boundary, the calculator shows both possible scores.
