How the estimate works
Each part of the exam is scaled to its share of the score: multiple choice is 70%, and free response is 30%. That gives a weighted total out of 100.
We estimate a 5 at about 84.5, a 4 at 73, a 3 at 57.5, and a 2 at 43.5. College Board has not openly posted a scoring chart for this exam, so the cut points here are the middle of the curves other calculators use.
The sources disagree by up to 16 points on a single cut, so when your total is within 8 points of one, the calculator shows a range such as “3 to 4” and does not pick.
The exam page describes the end-of-course exam as fully digital in Bluebook, with the Create performance task due April 30, 2027 and the exam on May 14, 2027; it states no recent change to question counts or weights.

Frequently asked questions
What score do I need for a 5 on AP CSP?
We estimate about 84.5% of the weighted total, and about 57.5% for a 3. College Board sets the real cut after each exam and does not publish it, and the sources we compared differ by up to 16 points.
How accurate is this AP CSP score calculator?
It is an estimate. College Board has not openly posted a scoring chart for this exam, so the cut points here are the middle of the curves other calculators use. Treat a result near a cut point as either score.
Is the AP CSP exam curved?
Not against other students. College Board sets the composite score needed for each AP score for that year’s exam form, so the cut points shift a little from year to year.
