Take a free AP Biology practice test built around the real AP exam format. FRQs are scored with point-by-point rubric feedback — the same breakdown AP graders use — so you see exactly what mechanism or connection each answer needed.
What's Included
- 60 Multiple-Choice Questions — 90 minutes, including grid-in questions
- 2 Long Free-Response Questions — 8–10 points each, including experimental design
- 4 Short Free-Response Questions — 4 points each, require mechanism-level explanations
AP Biology Exam Format
- MCQ (50%): 60 questions in 90 minutes — many include graphs, data tables, or experimental descriptions
- FRQ (50%): 6 questions in 90 minutes — 2 long (multipart) + 4 short
- Score distribution: ~14% score a 5; ~20% score a 4
Most-Tested Topics
- Unit 2 (Cell Structure and Function): Membrane transport mechanisms, organelle functions
- Unit 3 (Cellular Energetics): Photosynthesis and cellular respiration — comparing the two pathways is a perennial FRQ topic
- Unit 5 (Heredity): Meiosis, Mendelian and non-Mendelian genetics, probability calculations
- Unit 6 (Gene Expression): Transcription, translation, gene regulation, mutation effects
