AP Biology is organised into 8 units per the 2024 College Board Course & Exam Description. Our curriculum follows the same structure with per-unit teaching, FRQ practice, and unit-end mock assessments.
Unit 1
8-11%Water properties, biological macromolecules (carbohydrates, lipids, proteins, nucleic acids), and the chemistry of monomers and polymers. Foundational for all subsequent units.
Unit 2
10-13%Prokaryotic vs eukaryotic cells, organelles (mitochondria, chloroplasts, endomembrane system), membrane transport, compartmentalisation, and cell size / surface area relationships.
Unit 3
12-16%Enzymes (induced-fit, kinetics, regulation), cellular respiration (glycolysis, Krebs, electron transport), photosynthesis (light + Calvin cycle), and metabolic fitness.
Unit 4
10-15%Signal transduction pathways, feedback mechanisms, cell-cycle regulation, mitosis, and cancer biology basics.
Unit 5
8-11%Meiosis, Mendelian genetics, pedigree analysis, non-Mendelian inheritance, chromosomal inheritance, and Hardy-Weinberg equilibrium calculations.
Unit 6
12-16%DNA structure and replication, transcription, translation, gene expression regulation (operons, epigenetics), mutation types, and biotechnology (PCR, gel electrophoresis, cloning).
Unit 7
13-20%Evidence for evolution, mechanisms of evolution (selection, drift, gene flow, mutation), speciation, phylogenetics, and the origin of life. The largest AP Biology unit by weight.
Unit 8
10-15%Population ecology (logistic + exponential growth), community ecology, ecosystem dynamics, biogeochemical cycles, and human impact on ecosystems.
Two sections, 3 hours total, evenly weighted between MCQ and free-response. Calculator permitted throughout.
60 questions in 90 minutes. 50% of the exam score. Mix of standalone MCQs + question sets referencing data, experiments, or models.
6 FRQs in 90 minutes. 50% of the exam score. Includes 2 long-form questions (8-10 points each, one on interpreting/designing experiments) + 4 short-answer questions.
5 = extremely well qualified, 4 = well qualified, 3 = qualified (passing), 2 = possibly qualified, 1 = no recommendation. Most US colleges accept score 4+ for credit.
Our Complete AP Biology Year runs August to May, matching the US school calendar. Here is the phase-by-phase focus and what you should be doing each month.
Aug-Oct (Start of Junior Year)
Cover Units 1-3 (Chemistry, Cell Structure, Cellular Energetics). These are the most-tested topics by % of exam weight. Build note-taking system — flashcards for vocabulary, concept maps for pathways.
Nov-Jan
Work through Units 4-6 (Cell Communication, Heredity, Gene Expression). These dominate free-response questions. Start doing practice FRQs from past exams — at least 2 per week by December.
Feb-Mar
Cover Unit 7 (Natural Selection — largest unit) and Unit 8 (Ecology). Transition to full-length practice tests. Target 55+ raw score on MCQ + 35+ on FRQs for a likely 5.
Apr-May
Full-length timed tests weekly. Review weak areas via College Board CED and unit reviews. Exam is first week of May. Final week: rest + light review, not new material.
Weekly free-response questions with model answers + examiner-style rubric feedback. FRQs are where most 3s and 4s lose points — we drill them relentlessly from week 2.
Live classes scheduled for 6-9 PM ET weekdays plus Saturday 10 AM ET intensives. Fits standard US high-school evening study windows.
A 4 or 5 places most students out of introductory college biology, saving a semester of tuition. We teach to the College Board CED and the exact FRQ rubric so the score reflects real mastery, not test tricks.
The 8 units per College Board 2024 Course & Exam Description are: Unit 1 Chemistry of Life (8-11%), Unit 2 Cell Structure and Function (10-13%), Unit 3 Cellular Energetics (12-16%), Unit 4 Cell Communication and Cell Cycle (10-15%), Unit 5 Heredity (8-11%), Unit 6 Gene Expression and Regulation (12-16%), Unit 7 Natural Selection (13-20% — the largest unit), and Unit 8 Ecology (10-15%). Students should allocate prep time proportional to unit weight.
Two sections. Section I is 60 multiple-choice questions in 90 minutes (50% of score). Section II is 6 free-response questions in 90 minutes (50% of score) — 2 long-form (one asks students to design or interpret an experiment) plus 4 short-answer. Total exam: 3 hours. Calculator permitted throughout. Total score reported 1-5; most US colleges accept 4+ for credit.
AP Biology is built to mirror a two-semester college introductory biology course, so the difficulty comes less from memorisation and more from application. The exam rewards experimental design, data interpretation, and reasoning from the Big Ideas — most students who already know the content still lose points on free-response questions because they write what they know rather than what the rubric asks for. The two highest-weight, highest-difficulty units are Unit 3 (Cellular Energetics) and Unit 7 (Natural Selection, the single largest unit). Our coaching front-loads these and drills FRQs from week 2.
Both are common. Taking it in Grade 11 gives you the score in hand for college applications due in October-November of Grade 12 — this is the more strategic choice. Grade 12 timing works if you prefer spreading your AP load across years. Most US college admissions officers see AP Biology in Grade 11 as strong evidence of academic rigour, and a 4 or 5 can earn college credit, placing you out of introductory biology.
Our AP Biology coaching is fully online and scheduled to fit US time zones (6-9 PM ET evening batches, plus a Saturday 10 AM ET intensive). The curriculum follows the College Board Course & Exam Description with unit-by-unit teaching, weekly FRQ practice with rubric-style feedback, and two full-length practice exams before the May exam. We offer 1:1 premium mentoring and small-batch cohorts.
Our Complete AP Biology Year programme (Aug-May, covering the full curriculum + practice exams) is $1,800 flat. 1:1 Elite Mentoring is $90 per hour. The Small-Batch AP cohort (4-6 students) is $50 per hour. All pricing is in USD, and classes run live in your US time zone.
No — Indian medical admissions (AIIMS, JIPMER, and others) require a NEET-UG score; AP scores are not accepted. AP Biology is built for US and international college admissions. If you plan to return to India for medical school, see our dedicated AP-to-NEET bridge programme at /ap-biology-to-neet-preparation, which retools AP knowledge for the NEET pattern.
Free demo, no commitment. We confirm your grade, school, and AP exam year and assign a mentor within 15 minutes (working hours).
Same form, same promise.
