AP Computer Science Principles Score Calculator

Enter your points from a Computer Science Principles practice test to predict your 1–5 score. A 5 takes about 79 of 100 points.

How the AP Computer Science Principles exam is scored

The exam is 3 hours long. Multiple choice (70 questions) is 70% of your score and free response is 30%. The free response has two questions worth 3 points each. Each part is scaled by its weight and added into a composite out of 100, which is then converted to a score from 1 to 5.

What does it take to get a 5?

About 79 of 100 composite points, by our estimate. One way to get there is roughly 56 of 70 multiple choice questions right and 5 of 6 free-response points. A 4 takes about 65 points and a 3 about 53. In 2026, 10% of students earned a 5 and 63% earned a 3 or higher.

Where students lose points

The 70 multiple choice questions are 70% of the score. The other 30% is your Create performance task, including written responses you answer on exam day about your own program. Know exactly what your list and your procedure do, and keep the code segments in your Personalized Project Reference easy to point to.

About the calculator

How the estimate works and how to use it

Enter the points you expect on each part of the exam. Each section is weighted the way the College Board weights it, added into a total out of 100, and compared with estimated cut scores for a 5, 4, 3, and 2.
It is an estimate. The College Board sets new cut scores every year and does not publish them. Ours are based on the estimates other AP score calculators publish, so your real score can land a point either side.
The College Board's official AP score distributions for the most recent exam year.
Grade a practice free response with its scoring guidelines, the way AP readers do. The College Board posts past free-response questions with their scoring guidelines on AP Central.
Most colleges give credit for a 3 or higher, and selective colleges often ask for a 4 or 5. Check your college's AP credit policy for the exact rule.
Usually in early July, after the May exams. You see them in your College Board account.
