How the estimate works
Each part of the exam is scaled to its share of the score: multiple choice is 50%, and free response is 50%. That gives a weighted total out of 100.
We estimate a 5 at about 77.5, a 4 at 61.7, a 3 at 45, and a 2 at 25. The last scoring chart College Board posted openly for this exam is from 2013, the most recent one available. We combine it with the curves 2 other calculators use.
The sources disagree by up to 10 points on a single cut, so when your total is within 5 points of one, the calculator shows a range such as “3 to 4” and does not pick.
Hybrid digital exam: multiple choice is answered and free-response questions are viewed in Bluebook, with free-response answers handwritten in paper booklets. The exam page lists the exam date as May 3, 2027.

Frequently asked questions
What score do I need for a 5 on AP Bio?
We estimate about 77.5% of the weighted total, and about 45% 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 10 points.
How accurate is this AP Bio score calculator?
It is an estimate. The last scoring chart College Board posted openly for this exam is from 2013, the most recent one available. We combine it with the curves 2 other calculators use. Treat a result near a cut point as either score.
Is the AP Bio 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.
