AP Biology 2026: Fewer Perfect Scores—What Changed?
Last year, 18.9% of students earned a 5 in AP Biology. This year, that number has dropped to 15%.While the overall pass rate remains solid, the decline in top scores suggests one thing: earning a 5 is becoming more competitive.
My take? The most likely reasons are:
- More application-based and analytical questions testing deeper understanding rather than memorization.
- A larger and more diverse testing pool, making the top score harder to achieve.
- Students relying on content review without enough practice on AP-style reasoning and free-response questions
