Predicted AP score: 4Both sections are worth half the exam, so each contributes 75 of the 150 composite points. Sixty multiple-choice questions face 46 raw free-response points, which makes one free-response point worth about 1.63 composite points against 1.25 for a multiple-choice question.

AP Chemistry splits its composite exactly down the middle: Section I and Section II are each worth half the exam, and each contributes 75 of the 150 points. What makes that symmetry worth a second look is that the two halves are built from unequal raw material — 60 multiple-choice questions on one side, 46 free-response points on the other, from three long questions at 10 points and four short ones at 4. Each side is scaled on its own, so a question is worth 75 ÷ 60 = 1.25 composite points while a free-response point is worth 75 ÷ 46 ≈ 1.63.
The default entries show the whole path: 42 correct questions give 52.50, the 29 free-response points give 47.28, the composite is 99.78, and rounding to 100 puts it above the 85 needed for a 4 but below the 110 for a 5. Two test cases make the symmetry visible from the outside: a flawless multiple-choice section with nothing written scores 75, and a flawless free-response section with no correct question scores the same 75. Both are a 3, and neither half on its own can do better.
The limitation is the cut scores. 110, 85, 60 and 40 are read back from released scoring worksheets of 2022 to 2024 and move a few points per administration; the College Board does not confirm the current year's figures.
The 60 multiple-choice questions carry the first 75 points and the 46 raw free-response points the second 75. Both sections are worth half the exam.
A perfect multiple-choice section with nothing on the free response scores 75, and a perfect free response with no correct question scores the same 75. Both land on a 3.
110, 85, 60 and 40 were back-calculated from released scoring worksheets of those years and move a few points per administration. The College Board does not confirm current-year thresholds.
MisconceptionAll seven free-response questions are worth the same.
CorrectionThe three long questions carry 10 points each and the four short ones 4, which makes 46 raw points in total.
MisconceptionOne free-response point and one question move the composite equally.
CorrectionA free-response point is worth about 1.63 composite points, a multiple-choice question 1.25.

Each section is scaled to 75 points and the two are added, giving a composite from 0 to 150. Sixty multiple-choice questions carry the first 75 points, and the 46 raw free-response points carry the second 75.
Roughly 110 for a 5, 85 for a 4, 60 for a 3 and 40 for a 2. Anything below 40 is a 1.
Three long questions are worth 10 points each and four short ones 4 points each, so 46 raw points in total. Because those 46 points carry the same 75 composite points as 60 questions, a single free-response point is worth about 1.63 composite points.
No. A blank and a wrong answer both score zero, so answer all 60 questions even when you are down to a coin flip.
The section weighting is published and fixed, but the cut scores are not: the College Board withholds current-year thresholds, and they move a few composite points per administration. Self-marked free-response answers also tend to be more generous than an official reader.
