The AP Precalc exam format
AP Precalculus is a hybrid digital exam lasting 2 hours 55 minutes. It tests units 1–3 only (polynomial and rational functions; exponential and logarithmic functions; trigonometric and polar functions). Unit 4 is taught in many classes but is not on the exam.
- Multiple choice Part A: 29 questions, no calculator, 65 minutes, about 44%.
- Multiple choice Part B: 13 questions, graphing calculator required for some (radian mode), 40 minutes, about 19%.
- Free response Part A: 2 questions with a graphing calculator, 35 minutes: function concepts and modeling a non-periodic context.
- Free response Part B: 2 questions without a calculator, 35 minutes: modeling a periodic context and symbolic manipulations.
Each free-response question is worth 6 points, and the free-response section is about 37% of the score.
| Section | Scored out of | Weight |
|---|---|---|
| Multiple choice Part A (29, no calculator) | 29 questions | 44% |
| Multiple choice Part B (13, graphing calculator) | 13 questions | 19% |
| Free response Part A (calculator, 0–6 each) | 6 + 6 pts | 18.5% |
| Free response Part B (no calculator, 0–6 each) | 6 + 6 pts | 18.5% |
How this AP Precalc score estimate works
Multiple choice Part A: points ÷ 29 × 44 Multiple choice Part B: points ÷ 13 × 19 Free response Part A: points ÷ 12 × 18.5 Free response Part B: points ÷ 12 × 18.5 Composite = sum of the lines above (0–100)
By our estimate a 5 takes about 61 composite points, which an even performance reaches with 18 of 29 multiple-choice Part A questions, 8 of 13 multiple-choice Part B questions, 7 of 12 free-response Part A points and 7 of 12 free-response Part B points. A 3 takes about 37: 11 of 29 multiple-choice Part A questions, 5 of 13 multiple-choice Part B questions, 4 of 12 free-response Part A points and 4 of 12 free-response Part B points. These lines are educated guesses rather than published cut scores (why), so a result within two or three points of one could go either way.
| AP score | Estimated composite |
|---|---|
| 5 | 61–100 |
| 4 | 49–60 |
| 3 | 37–48 |
| 2 | 26–36 |
| 1 | 0–25 |
Worked example
Zoe gets 20 of 29 on Part A and 9 of 13 on Part B. Her free-response scores are 4 and 3 (calculator), then 3 and 4 (no calculator).
MC A: 20 ÷ 29 × 44 = 30.3
MC B: 9 ÷ 13 × 19 = 13.2
FR A: 7 ÷ 12 × 18.5 = 10.8
FR B: 7 ÷ 12 × 18.5 = 10.8
Composite: 65.1 → estimated 5
AP Precalculus has had generous results since its 2024 launch; in 2026, 29% scored a 5. Zoe’s composite is 4.1 points above our estimated 5 line.
AP Precalc scores in 2026
Precalculus had one of the highest pass rates in 2026: 82% scored 3 or higher and 58% scored a 4 or 5.
Tips for a higher AP Precalc score
- Part A multiple choice is the biggest chunk. Practise transformations, function composition, log rules and exact trig values without a calculator.
- Set your calculator to radians. The calculator sections assume radian mode.
- Model in context. The modeling questions ask you to build a function from data and interpret its parameters in the situation; units matter.
- Simplify fully in the symbolic question. Show each algebra or identity step; final answers alone may not earn all points.
Questions students ask
Is unit 4 on the AP Precalculus exam?
No. The exam covers units 1–3. Unit 4 (functions involving parameters, vectors and matrices) is part of the course but not tested.
How many free-response questions are on AP Precalc?
Four, each worth 6 points: two with a graphing calculator and two without. Together they are about 37% of the score.
Is AP Precalculus worth taking?
It prepares you for AP Calculus and may earn college credit. Check whether your target colleges award credit, since policies for this newer exam vary.
