Section II is 4 free-response questions in 1 hour 10 minutes and carries 37.5%. The exam runs 2 hours 55 minutes in total, and it is a fully digital exam completed in the Bluebook app.
| Section | Questions | Timing | Weight |
|---|---|---|---|
| Section I, Multiple Choice | 42 | 1 hour 45 minutes | 62.5% |
| Section II, Free Response | 4 | 1 hour 10 minutes | 37.5% |
Precalculus is one of the few AP exams where the multiple-choice section carries more than half the score, so MCQ accuracy matters more here than on a 50/50 exam. One extra correct multiple-choice answer is worth 1.49 composite points; one extra free-response point on a 40-point Section II is worth 0.94 points.
Free-response totals differ between practice exams, so enter the rubric total from the paper you are scoring rather than assuming a fixed number.
Every AP exam is scored in two stages. Your raw score, the number of multiple-choice questions you got right and the rubric points your written answers earned, is weighted by the official section weights into a composite score, and that composite is then mapped onto the 1–5 scale.
The second stage is the part no calculator can reproduce. College Board does not publish the composite cut points for any AP subject, and it adjusts them every year through a statistical process called equating, so that a 3 means the same thing even if one year's exam was slightly harder than another's.
We checked the cut points that prep sites publish and they do not agree with each other: one puts the 3-line at a 55% composite, another at 42%, another at 50%. When published estimates disagree by that much, quoting any one of them as a prediction would be guessing. So this page does the part that is actually deterministic, your weighted composite, computed from the official weights, and lets you set your own target and see exactly how much more you need to reach it.
Your raw score has two parts: the number of multiple-choice questions you answered correctly, and the rubric points your free-response answers earned. Each part is scaled to its section weight, and the two weighted parts are added into a composite score out of 100. That composite is then placed on the 1 to 5 scale.
Not exactly. College Board does not publish the composite cut points for this subject, and it recalculates them every year through equating to keep scores comparable across exam forms. What you can work out exactly is your weighted composite percentage, which is what the calculator above gives you, and that is the number to track while you study.
There is no published answer, and prep publishers who publish estimates disagree with each other by more than ten percentage points. Rather than quote a number that would be a guess, this page lets you enter your own target composite and tells you how many more correct answers or rubric points it takes to get there.
No. AP multiple-choice questions are scored as right or wrong with no penalty for a wrong answer, so a blank and a wrong answer cost exactly the same. Always fill in an answer, and always write something for every free-response part, rubric points are awarded for partial credit.
College Board publishes the exam structure for every AP subject on its official course pages: the number of questions, the timing, and the percentage of the exam score each section carries. Those weights are used here unchanged.
