If you have exactly three months until the AP Biology exam, you still have plenty of time to prepare — as long as you follow a structured and strategic plan. This 90-day study schedule is designed to cover all AP Biology units, give you ample practice with past College Board FRQs and MCQs, and leave time for full-length exam simulations.

Whether you’re aiming for a score of 5 or simply want to feel confident on test day, this plan will help you balance content review, practice questions, and exam strategy.

Why a 3-Month Plan Works

Three months is enough time to:

• Review all 8 AP Biology units without rushing.
• Practice applying concepts in free-response and multiple-choice formats.
• Identify weaknesses early and fix them before the exam.
• Simulate test conditions multiple times for endurance and pacing.

By following a weekly breakdown, you avoid the last-minute cramming trap.

Month 1 – Comprehensive Content Review & Light Practice

Goal: Cover all AP Biology units while starting light practice with MCQs and FRQs.

Week 1 – Unit 1 & Unit 2

• Topics: Chemistry of Life; Cell Structure and Function.
• Watch review videos (Bozeman Science, Khan Academy).
• Take past FRQs from these units (College Board archive).
• Do 25 MCQs per topic on AP Classroom or other question banks.

Week 2 – Unit 3 & Unit 4

• Topics: Cellular Energetics; Cell Communication and Cell Cycle.
• Summarize key equations (photosynthesis, cellular respiration).
• FRQ practice on energy transformations.
• 30 MCQs per unit with explanations.

Week 3 – Unit 5

• Topics: Heredity.
• Review Punnett squares, Mendelian and non-Mendelian inheritance.
• Practice FRQs on genetic crosses.
• 50 MCQs spread over two days.

Week 4 – Unit 6

• Topics: Gene Expression and Regulation.
• Master lac operon, transcription/translation, and epigenetics.
• 2 FRQs from past exams.
• 50 MCQs for reinforcement.

Month 2 – Advanced Content Review & Heavier Practice

Goal: Finish the remaining units and start integrating mixed-topic practice.

Week 5 – Unit 7

• Topics: Natural Selection.
• Create evolutionary evidence mind maps.
• FRQs on population genetics.
• 40 MCQs on evolution.

Week 6 – Unit 8

• Topics: Ecology.
• Review energy flow, trophic levels, and biogeochemical cycles.
• 2 FRQs on ecological interactions.
• 40 MCQs on ecology.

Week 7 – Mixed Review Week 1

• Review Units 1–4 intensively.
• Mixed MCQ sets (60 questions/day).
• FRQs: 2 full questions under timed conditions.

Week 8 – Mixed Review Week 2

• Review Units 5–8 intensively.
• Mixed MCQ sets (60 questions/day).
• FRQs: 2–3 timed questions.

Month 3 – Full Exam Simulations & Final Weakness Fixes

Goal: Transition from studying content to mastering pacing and endurance.

Week 9 – Full-Length Practice Exam #1

• Take a full past AP Biology exam from College Board under timed conditions.
• Review every question, especially wrong ones.
• Identify 3–4 weakest topics.

Week 10 – Weakness Fix & Targeted Practice

• Revisit weak units with targeted readings.
• 50 MCQs on problem areas.
• FRQs from those units only.

Week 11 – Full-Length Practice Exam #2

• Simulate test conditions again.
• Compare scores to Week 9.
• Focus final review on recurring mistakes.

Week 12 – Light Review & Exam Readiness

• Skim unit summaries.
• Do one last set of 30 MCQs.
• Practice 1 FRQ daily.
• Rest before exam day.

Key Study Tips for This Schedule

• Use Past FRQs: Go directly to the College Board AP Biology FRQ archive and practice with the official scoring guidelines.
• Time Yourself: The FRQ section is 90 minutes for 6 questions — train to finish in time.
• Analyze MCQs: Don’t just see the right answer — understand why others are wrong.
• Space Your Review: Come back to old material multiple times for retention.

FAQ – 3-Month AP Biology Study Plan

Q1: Can I still get a 5 with only 3 months left?
Yes — with a structured plan and consistent practice, many students score a 5 starting at this timeline.

Q2: Should I focus more on FRQs or MCQs?
Do both — but FRQs are often under-practiced, so give them extra attention.

Q3: Where can I find full-length practice exams?
College Board AP Classroom, Barron’s, Princeton Review, and released past exams.

Q4: How many hours per week should I study?
Plan for 7–10 hours weekly, increasing slightly in the final month.
