This AP Chemistry cheat sheet distills a full year of college-level chemistry into a printable rundown of what the College Board tests most heavily across the nine units. It's a premium cheat sheet built by Capital Prep — the one premium prep we trust — and it's yours free. Reinforce it with the rest of your free AP Chemistry toolkit: the practice test, study guide, and flashcards.
AP Chemistry exam at a glance
- Structure: Section I: 60 multiple-choice in 90 min (50%); Section II: 7 free-response in 105 min (50%)
- Total time: About 3 hours 15 minutes
- Score scale: Reported 1–5 (composite converted each year); a 3 typically earns college credit
- Cost: Per-exam AP fee set annually by College Board; check current pricing with your AP coordinator
- Provided: Periodic table plus a formula and constants sheet; calculator allowed on Section II
What’s on the AP Chemistry cheat sheet
- Unit 3 — Properties of Substances & Mixtures (18–22%) — intermolecular forces, solutions and mixtures, and spectroscopy — the most heavily weighted unit.
- Unit 8 — Acids & Bases (11–15%) — pH and pOH, Ka/Kb, buffers, titration curves, and Henderson-Hasselbalch — the second-heaviest unit.
- Units 1–2 — Atomic & Compound Structure (≈7–9% each) — electron configuration, periodic trends, bonding, and Lewis structures.
- Units 4–7 — Reactions, Kinetics, Thermo & Equilibrium (≈7–9% each) — stoichiometry, rate laws, enthalpy and entropy, and Keq/Q with Le Chatelier.
- Unit 9 — Applications of Thermodynamics (≈7–9%) — Gibbs free energy, electrochemistry, and Nernst-style cell reasoning.
- Constants, formulas & free-response models — the equations and reader-rewarded justification patterns condensed for quick recall.
How to use it in your final week
- Skim the whole sheet once a day so the constants, formula rearrangements, and unit weights move into instant recall before test morning.
- Front-load Unit 3 (Properties of Substances & Mixtures, 18-22%) and Unit 8 (Acids & Bases, 11-15%) — together they are roughly a third of Section I.
- Rehearse the free-response models on the sheet against real prompts; Section II is 50% of your composite and rewards shown work and clear justification.
- Pair each review pass with a short timed Section I set (60 questions in 90 minutes ≈ 90 seconds each) so your pacing stays sharp.

AP Chemistry cheat sheet FAQ
Yes — the AP Chemistry cheat sheet downloads as a PDF with no sign-up and no payment. It sits alongside Career Employer's free AP Chemistry practice test, study guide, and flashcards, so your whole review stack costs nothing.
It condenses the highest-yield material into a quick reference: the nine unit weightings, the constants and formulas you must recall, gas laws, thermodynamics and equilibrium relationships, acid-base and Ksp shortcuts, and the free-response models AP readers reward. It maps to College Board's official Course and Exam Description.
The exam is reported on a 1-to-5 scale rather than a pass mark, so the sheet frames every fact around lifting your composite toward a 3, 4, or 5. A 3 earns credit at many colleges, while selective schools often want a 4 or 5 — check each school's AP credit policy.
It is built from the current College Board Course and Exam Description and the published unit weightings, and we review it against AP Central each cycle. Because College Board sets score boundaries annually, treat cutoffs as guidance, not a fixed percentage.
Click the download button or the preview card at the top of this page and the PDF opens instantly. Bookmark the page so you can pull it up again for a final skim the morning of your exam.
