An AP Bio review is essential if you want to score high on the AP Biology exam. The test requires not only strong memorization of biological concepts but also the ability to apply them in data analysis, experimental design, and scientific reasoning.
This guide covers:
- AP Bio exam format and timing
- Scoring breakdown
- Key topics to review
- Study strategies for success
- Common mistakes to avoid
AP Bio Exam Format
The AP Biology exam is 3 hours long and divided into two sections:
- Section I – Multiple Choice (90 minutes): 60 questions, worth 50% of the score. Includes individual questions and sets based on graphs, experiments, and data tables.
- Section II – Free Response (90 minutes): 6 questions (2 long, 4 short), worth 50% of the score. Requires data analysis, experimental design, and short written responses.
AP Bio Scoring Breakdown
- Multiple Choice: 50% of score
- Free Response: 50% of score
Scores are reported on the 1–5 AP scale:
- 5 – Extremely well qualified
- 4 – Well qualified
- 3 – Qualified
- 2 – Possibly qualified
- 1 – No recommendation
Key Topics to Review for AP Bio
- Chemistry of life: Structure and function of biological macromolecules, properties of water
- Cell structure and function: Organelles, membranes, transport, cell communication
- Cellular energetics: Photosynthesis, cellular respiration, enzymes
- Cell cycle and genetics: Mitosis, meiosis, Mendelian genetics, gene expression
- Evolution: Natural selection, Hardy-Weinberg equilibrium, phylogeny
- Ecology: Energy flow, population dynamics, ecosystems
- Systems biology: Endocrine, nervous, immune, and other organ systems
- Experimental design: Hypotheses, variables, controls, and statistical analysis
Study Strategies for AP Bio Review
- Use active recall with flashcards and self-quizzing
- Practice free-response questions with timed conditions
- Review past AP Bio exams from the College Board
- Use concept maps to connect related topics
- Apply biology concepts to real-world examples to improve retention
Common Mistakes to Avoid
- Memorizing without understanding concepts
- Skipping practice for the free-response section
- Ignoring data analysis skills and graph interpretation
- Not reviewing laboratory experiments and procedures

Frequently Asked Questions (FAQ)
Q1: How long should I spend on AP Bio review?
A1: Ideally, start reviewing 2–3 months before the exam and study consistently.
Q2: Are there math questions on the AP Bio exam?
A2: Yes — expect questions involving statistical analysis, chi-square tests, and basic algebra.
Q3: How can I improve my free-response scores?
A3: Practice writing concise, evidence-based responses and include data interpretation when possible.
Q4: Do I need to memorize every biology term?
A4: Focus on understanding concepts and being able to apply them, rather than rote memorization.
