AP Biology Exam Structure
The AP Biology exam has two sections, each worth exactly 50% of your final score:
- Section I – MCQ: 60 questions in 90 minutes. 1 point per correct answer. No guessing penalty — always answer every question.
- Section II – FRQ: 6 questions in 90 minutes — 2 long FRQs worth 10 points each, and 4 short FRQs worth 4 points each. Total raw: 36 points.
The FRQ raw score is scaled to match the MCQ weight. Both scaled scores are summed for a composite out of 120.
