AP Chemistry · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Kinetics & Atomic Structure and Properties

  • Derive rate laws from initial-rate data by comparing trials in which one reactant concentration changes while the others are held constant, then state each reactant's order and the overall order.

  • Distinguish zero-, first-, and second-order kinetics by testing which integrated plot (concentration vs. time, natural log vs. time, reciprocal vs. time) is linear, and compute half-life from the appropriate expression.

  • Apply the Arrhenius equation to calculate activation energy from two rate-constant/temperature pairs and to predict how a temperature increase or catalyst changes the rate constant.

  • Write electron configurations and interpret photoelectron spectra to justify periodic trends in atomic radius, first ionization energy, and electron affinity.

Your checkpoint

A one-page kinetics decision flowchart plus twelve solved rate-law, half-life, and Arrhenius problems covering all three reaction orders, self-scored at 80 percent or higher.

Week 2

Thermochemistry & Compound Structure and Properties

  • Calculate enthalpy changes from calorimetry data, Hess's law cycles, and standard enthalpies of formation, explicitly tracking sign conventions and limiting heat loss assumptions.

  • Differentiate state functions from path functions and explain why bond-enthalpy sums give only approximate reaction enthalpies.

  • Draw Lewis structures, assign formal charges, and predict electron-domain and molecular geometry with VSEPR for species having up to six electron domains.

  • Rank boiling points of related substances from intermolecular force analysis and connect each ranking to specific structural features such as polarity, hydrogen bonding, and molecular size.

Your checkpoint

A fifteen-item problem set spanning calorimetry, Hess's law, VSEPR geometry, and intermolecular-force ranking, accompanied by a written error log naming each mistake type.

Week 3

Equilibrium

  • Write equilibrium constant expressions in Kc and Kp form and manipulate them for reversed, multiplied, and summed reactions.

  • Construct ICE tables to solve for equilibrium concentrations and percent dissociation, including cases requiring the small-x approximation and cases where it fails.

  • Apply Le Châtelier's principle to predict the direction of shift from changes in concentration, volume or pressure, and temperature, distinguishing changes in Q from changes in K.

  • Solve solubility and common-ion problems with Ksp, and use the reaction quotient compared with K to determine the direction of net change.

Your checkpoint

A timed ten-question equilibrium quiz completed in twenty-five minutes with full ICE-table work shown, self-scored, and corrected for every missed item.

Week 4

Acids and Bases

  • Identify conjugate acid-base pairs and rank acid strength using Ka and pKa values together with structural factors such as bond polarity, oxyanion electronegativity, and resonance stabilization.

  • Calculate pH, pOH, and all species concentrations for strong and weak acids and bases, including polyprotic systems and salt solutions.

  • Analyze titration curves by locating equivalence and half-equivalence points, selecting appropriate indicators, and computing pH in every region of strong-strong and weak-strong titrations.

  • Explain buffer behavior quantitatively with the Henderson-Hasselbalch equation and predict the pH change caused by adding a strong acid or strong base.

Your checkpoint

Two fully annotated titration curves with calculated pH values in four regions each, plus ten buffer problems solved with Henderson-Hasselbalch and checked against mass-balance reasoning.

Week 5

Thermodynamics and Electrochemistry

  • Predict the sign and approximate magnitude of standard entropy change from particle count and phase changes, and calculate standard free energy change from enthalpy, entropy, and temperature.

  • Determine spontaneity and the crossover temperature by solving the free energy equation set equal to zero.

  • Convert among standard free energy change, equilibrium constant, and standard cell potential using the linking equations, and check each conversion for consistent units and significant figures.

  • Balance redox half-reactions in acidic and basic media, compute cell potentials for galvanic cells, and identify anode, cathode, and electron flow direction.

  • Apply the Nernst equation to nonstandard concentrations and use Faraday stoichiometry to calculate mass or charge in electrolysis.

Your checkpoint

A concept map linking free energy change, equilibrium constant, cell potential, and spontaneity with a worked numerical example on every arrow, plus twelve electrochemistry problems.

Week 6

Properties of Substances and Mixtures & Chemical Reactions

  • Classify ionic, molecular, covalent-network, and metallic solids by melting point, hardness, and conductivity, and justify each property from the underlying structure.

  • Interpret phase diagrams and heating curves by labeling coexistence regions and calculating the energy transferred in each segment.

  • Apply gas laws and colligative properties to solution problems, including vapor-pressure lowering and boiling-point elevation.

  • Write balanced molecular, complete ionic, and net ionic equations for precipitation, acid-base, and redox reactions in aqueous solution.

  • Predict products and classify reaction types, including combustion and gas-forming reactions, directly from reactant formulas.

Your checkpoint

A twenty-item mixed set with ten particulate, phase, and solution items and ten reaction-prediction and net-ionic items, scored to 85 percent or higher.

Week 7

Atomic Structure and Properties & Compound Structure and Properties & Properties of Substances and Mixtures & Chemical Reactions & Kinetics & Thermochemistry & Equilibrium & Acids and Bases & Thermodynamics and Electrochemistry

  • Reconstruct a one-page formula and constants sheet from memory, then verify every entry against the official reference table and mark gaps.

  • Complete two timed free-response sets under exam timing, writing every answer with explicit justification and unit-bearing calculations.

  • Re-derive from scratch, without notes, the five relationships missed most often across the first six weeks.

  • Audit the accumulated error logs and reattempt every previously missed item until each is answered correctly twice in a row.

Your checkpoint

Two graded free-response sets scored against an official-style rubric, plus a rewritten error log showing every previously missed item now solved correctly.

Week 8

Kinetics & Thermochemistry & Equilibrium & Acids and Bases & Thermodynamics and Electrochemistry

  • Complete one full-length timed practice exam in a single sitting under exam conditions, including the seventy-five-minute multiple-choice section and the free-response section.

  • Classify every miss by domain and by error type: content gap, calculation slip, misread question, or pacing.

  • Rebuild the three weakest sub-topics with targeted drills and retest each one under time pressure.

  • Rehearse pacing strategy, allocating roughly ninety seconds per multiple-choice item and splitting free-response time by point value.

Your checkpoint

A scored full-length exam with a per-domain accuracy table and a one-page final review sheet listing the ten facts and equations most likely to be forgotten under pressure.

Milestones

Week 2: Score at least 75 percent on a self-made twenty-question quiz drawn only from Weeks 1 and 2 goals, and explain aloud, without notes, how rate order, activation energy, and enthalpy of formation are determined.

Week 4: Score at least 70 percent on a thirty-question mid-plan assessment spanning kinetics, thermochemistry, equilibrium, and acids and bases, then list the three highest-error topics to schedule for Weeks 5 and 6.

Week 6: Complete every domain at least once and score at least 80 percent on a twenty-question cumulative quiz mixing all nine domains, with no domain below 60 percent accuracy.

Week 8: Achieve at least 75 percent overall on the full-length timed practice exam, with no single domain below 60 percent and every previously logged error resolved correctly twice.
