The short answer
AP CSA composite = MCQ correct ÷ 42 × 55 + Free Response points ÷ 36 × 45. An estimated 5 needs about 67% of the weighted composite, a 4 about 53% and a 3 about 40% (single third-party estimate (RemNote score calculator, “based on previously released exams”; not published by College Board)). Example: 65% of multiple choice plus 60% of free-response credit = 62.8 → about a 4.How the AP CSA score is calculated
The calculator adds up each part of the exam using College Board’s section weights:
composite % = MCQ correct ÷ 42 × 55 + Free Response points ÷ 36 × 45
The composite (0–100) is then compared with estimated cutoffs for a 5, 4, 3 and 2. Worked example: with 65% of the multiple-choice questions right (about 27 of 42) and 60% of the free-response credit, your composite is 55 × 0.65 + 45 × 0.6 = 62.8, which maps to an estimated 4. Each question is scored 0–9, 36 points in total (College Board 2025 scoring statistics).

Estimated AP CSA cutoffs
| Estimated AP score | Composite needed (of 100) |
|---|---|
| 5 | 67 or higher |
| 4 | 53 – 67 |
| 3 | 40 – 53 |
| 2 | 28 – 40 |
| 1 | below 28 |
Basis: single third-party estimate (RemNote score calculator, “based on previously released exams”; not published by College Board). College Board does not publish current cut scores, so treat every number in this table as an estimate with a margin of a few points.
What you need for a 3, 4 or 5 on AP CSA
Free-response result needed at three multiple-choice levels, using the estimated cutoffs above (assumes the same % correct on every multiple-choice part):
| Multiple choice correct | For a 3 | For a 4 | For a 5 |
|---|---|---|---|
| 50% (≈21 of 42) | 10 of 36 FRQ points | 21 of 36 FRQ points | 32 of 36 FRQ points |
| 65% (≈27 of 42) | 4 of 36 FRQ points | 14 of 36 FRQ points | 25 of 36 FRQ points |
| 80% (≈34 of 42) | reached with MCQ alone | 8 of 36 FRQ points | 19 of 36 FRQ points |
