AP Precalculus score calculator
On the AP Precalculus exam, the 42 multiple-choice questions are 62.5% of your score and the free response, four questions worth 6 points each, the other 37.5%, so one free-response point counts as much as about one multiple-choice answer. Enter your practice marks for your score out of 100 on those weights. The College Board publishes no chart that turns it into a 1 to 5, so this page does not guess one.
Example: weighted AP Precalc score
44.7 from multiple choice (30 of 42) + 23.4 from free response (15 of 24), by the College Board’s weights: 62.5% and 37.5%.
One more multiple-choice answer adds 1.51 in Part A and 1.44 in Part B, and one more free-response point 1.56.
To reach 70 of 100: 17 of the 24 free-response points with your 30 multiple-choice answers (2 more than now), or 32 of the 42 multiple-choice answers with your free response as it is (2 more).

The College Board publishes no chart that turns this into a 1 to 5 for today’s exam, so this is not your AP score.

How the weighted score is worked out
- The exam: 42 multiple-choice questions (Part A, 29 without a calculator in 65 minutes, for 43.75% of the score; Part B, 13 with a graphing calculator in 40 minutes, for 18.75%), then 4 free-response questions in 1 hour 10 minutes.
- Multiple choice: each part’s answers right ÷ its questions × its share: Part A ÷ 29 × 43.75, Part B ÷ 13 × 18.75. An answer is worth 1.51 in Part A and 1.44 in Part B.
- Free response: add your question scores (out of 24), then ÷ 24 × 37.5. Each point is worth 1.56.
- Add the two: a score out of 100 with the sections in the College Board’s proportions, 62.5% and 37.5%.
The College Board does not say how it combines the sections into the composite behind your AP score, only what share each section has, so this is the plainest reading of those shares.
The multiple choice changes in May 2027: 42 questions, 29 without a calculator in 65 minutes and 13 with a graphing calculator in 40 minutes. The exams up to May 2026, and practice exams taken from them, have 40: 28 without a calculator and 12 with one. Each part keeps its share, 43.75% and 18.75%, so on the earlier exams every multiple-choice answer counts the same. The free response stays four questions of 6 points, in 35 minutes a part instead of 30. On a 40-question exam each multiple-choice answer is worth 1.56.
A worked example
21 of 29 in Part A: 21 ÷ 29 × 43.75 = 31.7; 9 of 13 in Part B: 9 ÷ 13 × 18.75 = 13.0, so 44.7 from multiple choice. Free-response scores of 4, 4, 3 and 4 make 15 of 24: 15 ÷ 24 × 37.5 = 23.4. Together 68.1 of 100.
Where the next points are: a multiple-choice answer adds 1.51 in Part A and 1.44 in Part B and a free-response point 1.56, so one free-response point counts as much as about one multiple-choice answer.
What each free-response question is worth
Each question’s points are from the College Board’s 2026 scoring guidelines; its share of your 100 follows from the 37.5% the free response carries.
| Question | What it asks | Points | Of your 100 | As many Part A answers as |
|---|---|---|---|---|
| Question 1 | Function concepts | 6 | 9.4 | 6.2 |
| Question 2 | Modeling a non-periodic context | 6 | 9.4 | 6.2 |
| Question 3 | Modeling a periodic context | 6 | 9.4 | 6.2 |
| Question 4 | Symbolic manipulations | 6 | 9.4 | 6.2 |

Why there is no 1 to 5 here
The College Board sets the composite each AP score needs after every exam and publishes no chart for today’s AP Precalc exam. A 1 to 5 from any calculator is someone’s guess at those cut points.
What it does publish is how students scored. In 2026: 29% a 5, 29% a 4, 24% a 3, 11% a 2 and 7% a 1; 82% scored a 3 or higher. Those are shares of students, not the marks each score needed.
