How the AP Precalc exam is scored
AP Precalculus has 40 multiple choice questions (28 without a calculator, 12 with) worth 62.5% and four free-response questions scored 0 to 6 each worth 37.5%. The free-response questions have fixed types: function concepts, modeling a non-periodic context, modeling a periodic context, and symbolic manipulations. The exam launched in 2024 and has a comparatively high pass rate.
| Section | Questions or points | Weight | Composite points per raw point |
|---|---|---|---|
| Multiple choice | 40 questions | 62.5% | 1.56 |
| Free response | 4 questions, 24 points | 37.5% | 1.56 |
Composite formula
Each section's raw score is turned into a share of the section's weight, and the shares are added. The result is a composite on a 0 to 100 scale, which is the same proportion as the College Board's raw composite for this exam:
composite = multiple choice / 40 x 62.5
+ free response / 24 x 37.5Put another way, one multiple choice question is worth 1.56 composite points, while one point on the free response questions is worth 1.56. That ratio tells you where an hour of practice moves your score the most.
Estimated AP Precalc score cutoffs
Cutoffs vary by year; these are estimates from released exams and practice scoring guides. The College Board equates each exam after it is given and does not publish the current year's cutoffs.
| AP score | Meaning | Composite needed (of 100) | Multiple choice alone, with the example free response |
|---|---|---|---|
| 5 | extremely well qualified | 72 | 31 of 40 |
| 4 | well qualified | 60 | 23 of 40 |
| 3 | qualified | 46 | 14 of 40 |
| 2 | possibly qualified | 34 | 6 of 40 |
| 1 | no recommendation | below 34 |
Worked example: the form defaults
The calculator starts at about 70% of the maximum on every part. Here is the full arithmetic for those numbers:
| Section | Raw | Calculation | Composite points |
|---|---|---|---|
| Multiple choice | 28 of 40 | 28 / 40 x 62.5 | 43.75 |
| Free response | 16 of 24 | 16 / 24 x 37.5 | 25 |
| Composite | 68.75 |
A composite of 68.8 is a 4 under the estimated cutoffs (a 5 starts at 72, so it is 3.3 points short). Holding the free-response scores fixed, 31 multiple choice correct instead of 28 would reach a 5.
Where to gain points on AP Precalc
Because the composite is a weighted sum, every raw point has a fixed value, and they are not equal. On this exam a multiple choice question is worth 1.56 composite points and a free response point 1.56, so multiple choice questions are the more valuable unit, and they are also the easier ones to pick up by eliminating wrong answers. Free-response rubrics award points for specific moves (a thesis, a labeled graph, a unit, a justification), so learning what the graders look for usually adds points faster than more content review. On multiple choice, the lack of a guessing penalty means every blank is a wasted chance.
What the score means for college credit
Colleges set their own AP credit policies. Most public universities grant credit or placement for a 3 on AP Precalc; many selective private colleges require a 4 or 5, and some grant placement but not credit. The College Board's credit policy search lists each college's rule by exam. Scores stay in your account, and you can withhold or cancel a score before it is sent if you would rather a college not see it.
Predicted scores are estimates. Section weights follow the College Board course and exam description for AP Precalculus; the composite-to-score cutoffs are estimated from released exams and change each year when the College Board sets the curve. See every subject on the AP score calculator hub.
