Structure and bonding
Electron configuration, photoelectron spectra, and how shape explains properties.
AP Chemistry is a quantitative college-level course. The exam mixes multiple-choice calculation and explanation items with free-response that asks for work, units, and a particle-level sentence, not only a numeric answer.
Units include atomic structure, bonding, intermolecular forces, reactions, kinetics, thermodynamics, equilibrium, and acids and bases. The course and exam description also requires science practices: representing data, using mathematics, and explaining at the particulate level.
A calculator is allowed on part of the exam and forbidden on another. Cards should make you start the setup without looking up the identity. Lab work shows up as experimental-design and error items. Keep a particle-level sentence on the same card as the first equation so the two skills stay attached.
Electron configuration, photoelectron spectra, and how shape explains properties.
Limiting reactant, titration, and net ionic equations you can write fast.
Rate laws, energy diagrams, enthalpy, and entropy signs.
K versus Q, Le Chatelier, and buffer calculations.
Designed to sit beside class. If your school finishes content in March, start the mixed phase earlier.
Weeks 1–8
Card the identities you still derive slowly. After each quiz, add only the setup you missed, with units on the back.
Weeks 9–14
Write free-response under time, including the explanation sentence. Card the step you skip when you rush.
Weeks 15–18
Mixed multiple-choice with and without a calculator mindset. Stop adding new identities in the last week.
AP Chemistry cards should open a calculation or a particulate explanation. “Define enthalpy” is weaker than “write the expression you need and say what a negative ΔG means for K.”
Spaced repetition keeps identities available across a long course. Live problem sets still teach the algebra. Use both, and keep the deck smaller than the textbook.
Cover the solution and write the first equation plus units.
Explain a macroscopic change with particles, then flip.
Give concentrations and ask which way the reaction shifts.
280 setup and explanation cards at 25 minutes a day. Problem sets are extra.
Estimate: 30 seconds per new card, 10 seconds per review. Fixed review gaps, not FSRS or a recall prediction.
Your calculator inputs stay in this browser tab. No uploads, email or signup needed.
College Board publishes the current calculator policy. Practice both with and without one because sections differ.
Card reaction types you still cannot start. AP Chemistry is not an organic named-reaction exam.
Card the purpose of a control, a likely error, and the next measurement. Skip the full procedure.
The skills overlap. The paper style, practical endorsement, and topic lists are different examination systems.
