The short answer
APES composite = MCQ correct ÷ 80 × 60 + Free Response points ÷ 30 × 40. An estimated 5 needs about 66% of the weighted composite, a 4 about 52% and a 3 about 39% (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 = 63.0 → about a 4.How the APES score is calculated
The calculator adds up each part of the exam using College Board’s section weights:
composite % = MCQ correct ÷ 80 × 60 + Free Response points ÷ 30 × 40
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 52 of 80) and 60% of the free-response credit, your composite is 60 × 0.65 + 40 × 0.6 = 63.0, which maps to an estimated 4. Each question is scored 0–10, 30 points in total (College Board 2025 scoring statistics).

What you need for a 3, 4 or 5 on APES
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% (≈40 of 80) | 7 of 30 FRQ points | 17 of 30 FRQ points | 27 of 30 FRQ points |
| 65% (≈52 of 80) | reached with MCQ alone | 10 of 30 FRQ points | 21 of 30 FRQ points |
| 80% (≈64 of 80) | reached with MCQ alone | 3 of 30 FRQ points | 14 of 30 FRQ points |
