Result: 3Both sections are worth half the exam, so each carries 50 of the 100 composite points. 42 multiple-choice questions face 40 raw free-response points, making a question worth 1.19 composite points against 1.25 for a free-response point. The 1–5 boundaries are an estimate.

AP Physics 1 splits its composite exactly down the middle: Section I and Section II are each worth half the exam, so each carries 50 of the 100 points. What makes that symmetry worth a look is that the two halves are built from unequal raw material — 42 multiple-choice questions on one side, 40 free-response points on the other, from four questions worth 10, 12, 10 and 8. Each side is scaled on its own, so a question is worth 50 ÷ 42 ≈ 1.19 composite points while a free-response point is worth 50 ÷ 40 = 1.25. Question 2, translation between representations, is the heaviest single item on the paper: its 12 points are 15 composite points, more than a seventh of the whole exam. Two test cases make the symmetry visible from outside the formula: a flawless multiple-choice section with four blank free-response questions scores 50, and a flawless free-response section with no correct question scores the same 50. Both land on a 3, and neither half alone can do better. The limitation is the cut line. The College Board publishes the 50/50 weighting and the per-question points, but never the composite a 5 requires — not for this exam, not for any exam, in any year. The boundaries used here, 71, 60, 49 and 38, are an estimate and move a few points each year.
The 42 multiple-choice questions carry the first 50 points and the 40 raw free-response points the second 50. Both sections are worth half the exam.
A perfect multiple-choice section with nothing written scores 50, and a perfect free-response section with no correct question scores the same 50. Both are a 3.
The College Board has never published a composite-to-score table for any AP exam in any year. 71, 60, 49 and 38 are rescaled from the last practice-exam conversion published for this exam and shift a few points each administration.
All four free-response questions are worth the same.
On the 2025 exam they are worth 10, 12, 10 and 8 points, so 40 raw points in total — question 2 is half again as heavy as question 4.
A free-response point and a question move the composite equally.
A free-response point is worth 1.25 composite points, a multiple-choice question about 1.19.

| 42, 10, 12, 10, 8 | 100.00 | 5 |

Each section is scaled to 50 points and the two are added, giving a composite from 0 to 100. The 42 multiple-choice questions carry the first 50 points and the 40 raw free-response points carry the second 50.
Roughly 71 for a 5, 60 for a 4, 49 for a 3 and 38 for a 2, with anything below that a 1. These are estimates, not published figures.
On the 2025 exam question 1 is worth 10 points, question 2 twelve, question 3 ten and question 4 eight — 40 raw points in total. Question 2 is therefore the heaviest single item on the paper.
The 2025 exam: 42 multiple-choice questions at 50 %, four free-response questions at 50 %, with the 10/12/10/8 point split from the 2025 scoring guidelines.
The section weighting and the per-question points are published and exact, so the composite is reliable. The 1–5 boundaries are not published by the College Board and move a few points every year, and self-marked free-response answers tend to be more generous than an official reader.
