Exam format reminder: 60 MCQs (90 min) plus 6 FRQs (90 min). Two long FRQs (worth about 8-10 points each) and four short FRQs (worth 4 points each). Section 1 and 2 are each 50% of your score.
The 8-week schedule
| Week | Focus | What to actually do |
|---|---|---|
| Week 1 Mar 16 | Units 1 & 2: Chemistry of Life + Cell Structure | Water properties, macromolecules, membranes, transport, organelles. 20 released MCQs. Focus on identifying molecule types from structural diagrams. |
| Week 2 Mar 23 | Unit 3: Cellular Energetics | Enzymes, photosynthesis (light-dependent and Calvin cycle), cellular respiration (glycolysis, Krebs, ETC), fermentation. Highest-weight unit at 12-16%. 25 problems + 1 FRQ. |
| Week 3 Mar 30 | Units 4 & 5: Cell Communication + Cell Cycle | Signal transduction, feedback loops, mitosis, meiosis, cell cycle checkpoints. Common short FRQ topic. 2 timed FRQs. |
| Week 4 Apr 6 | Unit 5 & 6: Heredity + Gene Expression | Mendelian genetics, Punnett squares, DNA structure, replication, transcription, translation, mutations, gene regulation. Unit 6 is 12-16% (second highest). 2 FRQs. |
| Week 5 Apr 13 | Units 7 & 8: Natural Selection + Ecology | Hardy-Weinberg, evolution mechanisms, phylogenetic trees, population ecology, ecosystems, biodiversity. Take Practice Exam 1 at end of week under real timing. |
| Week 6 Apr 20 | Data analysis intensive | AP Bio is heavily data-driven. Practice reading experimental graphs, error bars, controls, chi-square problems, standard error. Redo missed MCQs from Practice Exam 1. 1 grid-in every session. |
| Week 7 Apr 27 | Practice Exam 2 + weak-area targeting | Take Practice Exam 2. Compare score to week 5. Target every weak unit. 3 FRQs per session with focus on the long FRQ format. |
| Week 8 May 4 | Sharpen & rest | Short spaced review across all 8 units. 2 FRQs per day Mon-Thu. Fri-Sun: flashcards, formula sheet, sleep. May 12 is exam day. |

The College Board publishes approximate weight ranges. Weight your study time accordingly.
- Unit 1 (Chemistry of Life): 8-11%
- Unit 2 (Cell Structure & Function): 10-13%
- Unit 3 (Cellular Energetics): 12-16% (front-load this)
- Unit 4 (Cell Communication & Cell Cycle): 10-15%
- Unit 5 (Heredity): 8-11%
- Unit 6 (Gene Expression & Regulation): 12-16% (front-load this)
- Unit 7 (Natural Selection): 13-20%
- Unit 8 (Ecology): 10-15%
What most AP Bio students get wrong
They over-study memorizable content (photosynthesis diagrams) and under-study experimental design. Half the exam requires you to interpret data, not recall facts. Reserve at least one full week for graph reading and experimental analysis.
They skip the AP Bio equations sheet. You get one on exam day. It has statistical formulas (chi-square, standard error), Hardy-Weinberg, and rate calculations. Practice with it in front of you every session from week 3 on.
They wait too long to write long FRQs. The two long FRQs are worth roughly half your FRQ points. Practice at least one per week starting week 4.
The 4-week compressed version
- Week 1: Units 1, 2, 3 (through cellular energetics). 15 MCQs per unit.
- Week 2: Units 4, 5, 6. Practice Exam 1 at end of week.
- Week 3: Units 7, 8. Data analysis practice. Practice Exam 2.
- Week 4: Weak-area targeting Mon-Wed. Rest Thu-Sun.
