Frequently asked
What is a good score on AP Biology?
On AP Biology, about 9% of students earn the top score of 5, and a 3 is the passing score, per recent College Board data. An estimated 70% composite reaches a 5 and 45% reaches a 3.
How is AP Biology scored?
Your raw MC and free-response points combine into a weighted composite (MC ~50%, FRQ ~50%), then map to the 1-5 scale. The exact mapping changes slightly each year, so this is an estimate.
Is this the official Bio curve?
No. College Board does not publish exact annual cut scores. These are estimates based on publicly released scoring worksheets, updated for 2025-26.
When do AP scores come out?
AP exams are in May and scores typically release in early-to-mid July. Use this calculator beforehand to estimate where you'll land.
