Ap Bio Score Breakdown: Raw Points to Composite Score Conversion Chart
Raw point cutoffs fluctuate slightly between annual test editions due to post-exam equating, a statistical process that accounts for minor variations in form difficulty. The following conversion framework reflects recent College Board operational benchmarks and provides a reliable practice exam score predictor.
| Scaled Score | Composite Cutoff (Out of 120) | Section 1 Target (Out of 60) | Section 2 Target (Out of 40 Raw) | Typical Distribution (%) |
|---|---|---|---|---|
| 5 | 92, 120 | 48, 55 | 30, 36 | 14%, 16% |
| 4 | 76, 91 | 40, 47 | 24, 29 | 22%, 24% |
| 3 | 59, 75 | 32, 39 | 18, 23 | 26%, 28% |
| 2 | 44, 58 | 24, 31 | 13, 17 | 22%, 24% |
| 1 | 0, 43 | 0, 23 | 0, 12 | 10%, 12% |
A score of 5 does not require perfection. Hitting approximately 77% of the available composite credit routinely places candidates in the top score bracket. A score of 3, the standard requirement for college credit at most public universities, requires just under half of the available weighted marks.
