Enter your multiple-choice and free-response results from an AP practice exam and get your weighted composite score out of 100, using the official College Board section weights, plus exactly how much more you need to hit the target you set.
| Input | Result |
|---|---|
| 48 of 60 MCQ at 50% weight, 24 of 34 FRQ points, target 70 | Composite 75.3%, 5.3 points above target |
| 30 of 60 MCQ at 50% weight, 15 of 34 FRQ points, target 70 | Composite 47.1%, needs 28 more MCQ answers or 16 more FRQ points |
| 55 of 75 MCQ at 67% weight, 10 of 14 FRQ points, target 70 | Composite 72.7%, 2.7 points above target |
Run a full practice exam under timed conditions, then score it honestly. Count how many multiple-choice questions you got right out of the total, and mark your free-response answers against the published scoring rubric to get the points you earned out of the points available. Enter the section weight for your subject, the table further down this page lists the official weights, and most science and maths exams split 50/50.
The useful output here is not a single number but the distance to your target. If you are eight composite points short, the calculator tells you that closing the gap takes eleven more correct multiple-choice answers or six more rubric points, and whichever of those is easier is where your next week of study should go.
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.
These are the weights College Board publishes on each course page. They are the only part of the score calculation that is public and fixed, and they are what the calculator above uses.
| AP subject | Section I (multiple choice) | Weight | Section II (written) | Weight |
|---|---|---|---|---|
| Biology | 60 multiple-choice questions, 90 minutes | 50% | 6 free-response questions, 90 minutes (9 + 9 + 4 + 4 + 4 + 4 = 34 points) | 50% |
| Chemistry | 60 multiple-choice questions, 90 minutes | 50% | 7 free-response questions, 105 minutes | 50% |
| Psychology | 75 multiple-choice questions, 90 minutes | 67% | 2 free-response questions, 70 minutes | 33% |
| Calculus AB | 42 multiple-choice questions, 100 minutes | 50% | 6 free-response questions, 90 minutes | 50% |
| Precalculus | 42 multiple-choice questions, 105 minutes | 62.5% | 4 free-response questions, 70 minutes | 37.5% |
| United States History | 55 multiple-choice questions, 55 minutes | 40% | 3 short-answer questions, 40 minutes (20%) + 2 free-response questions, 100 minutes (40%) | 20% + 40% |

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 your 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.
