The AP Biology exam is one of the most content-heavy AP tests, requiring mastery of complex biological concepts, data analysis, and application of scientific practices. A strong review plan can mean the difference between a passing score and a 5.
This guide covers:
- AP Bio exam structure
- How the exam is scored
- Key topics to review
- Study strategies and test-day tips
- Common mistakes to avoid
AP Bio Exam Structure
The AP Biology exam is 3 hours long and divided into two main sections:
Section I – Multiple Choice and Grid-In Questions
- 60 multiple-choice questions
- 6 grid-in questions (numeric answers)
- 90 minutes total
- Worth 50% of the overall score
Section II – Free Response Questions (FRQ)
- 2 long free response questions
- 4 short free response questions
- 90 minutes total
- Worth 50% of the overall score
How the AP Bio Exam Is Scored
The College Board uses weighted scoring to combine your Section I and Section II scores.
- Section I: 50% of the total score
- Section II: 50% of the total score
Final scores are converted to 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
The AP Biology curriculum is based on four big ideas:
- Evolution: Natural selection, speciation, phylogenetics
- Cell Processes: Cell structure, membrane transport, cellular respiration, photosynthesis
- Genetics and Information Transfer: DNA structure/function, transcription, translation, gene regulation
- Ecology and Interactions: Population dynamics, energy flow, biogeochemical cycles
You should also be familiar with:
- Statistical analysis (chi-square tests, standard error, mean, median, mode)
- Experimental design principles
- Interpreting and constructing graphs/data tables
Study Strategies for AP Bio Review
- Start with your weakest topics: Use practice tests to identify gaps in your knowledge.
- Practice with past FRQs: Focus on using precise biological terminology in your answers.
- Use diagrams and visuals: Biology concepts are easier to remember with labeled diagrams.
- Learn the labs: The College Board’s 13 AP Bio labs often appear in FRQs.
- Review data analysis skills: Many questions involve interpreting experimental results.
Test-Day Tips for AP Bio
- Read questions carefully — look for keywords like "justify" or "explain" that require full reasoning.
- Manage your time — don’t spend too long on one question.
- For FRQs, outline your answer before writing to stay organized.
- Label all graphs and include units when applicable.
Common Mistakes to Avoid
- Misinterpreting experimental data
- Forgetting to connect evidence back to the claim in FRQs
- Using vague or incorrect terminology
- Ignoring statistical reasoning in data analysis questions
Why AP Bio Review Is Essential
The AP Biology exam requires both content knowledge and analytical skills. A well-structured review helps you recall complex material quickly, apply it to new scenarios, and maximize your score potential.

Frequently Asked Questions (FAQ)
Q1: How much time should I spend on AP Bio review?
A1: At least 1–2 hours per week during the year, increasing to daily review in the final month.
Q2: Are AP Bio FRQs harder than multiple choice?
A2: They can be, as they require detailed explanations and application of concepts rather than simple recall.
Q3: Do I need to memorize all the labs?
A3: Yes — understanding the labs and their experimental design is essential for FRQs.
Q4: What’s the best way to prepare for AP Bio?
A4: Combine content review with practice exams and past FRQs for a balanced approach.
