Exam format reminder: 60 MCQs (90 min, 50% of score) plus 7 FRQs (105 min, 50% of score). The FRQ section includes 3 long questions and 4 short questions. You are given a periodic table and formula reference sheet for both sections.
The 8-week schedule
| Week | Focus | What to actually do |
|---|---|---|
| Week 1 Mar 9 | Units 1 & 2: Atomic Structure + Molecular and Ionic Compounds | Electron configuration, periodic trends (atomic radius, IE, electronegativity), VSEPR, bond polarity, Lewis structures, formal charge, resonance. 20 released MCQs. Practice drawing Lewis structures for 10 molecules per session. |
| Week 2 Mar 16 | Unit 3: Intermolecular Forces and Properties | Identify and rank IMF types, phase diagrams (triple point, critical point), heating and cooling curves (phase changes vs. temperature changes), solution chemistry, vapor pressure, colligative properties. Highest-weight unit at 18-22%. 25 problems + 1 timed FRQ on phase behavior. |
| Week 3 Mar 23 | Units 4 & 5: Chemical Reactions + Kinetics | Reaction types (synthesis, decomposition, combustion, acid-base, oxidation-reduction), net ionic equations, stoichiometry, limiting reagent problems, rate laws from experimental data, integrated rate laws (zero/first/second order), Arrhenius equation and activation energy. 20 MCQs, 1 FRQ on rate law determination. |
| Week 4 Mar 30 | Units 6 & 7: Thermodynamics + Equilibrium | Enthalpy (Hess's law, bond enthalpies, calorimetry), entropy trends, Gibbs free energy and spontaneity, Kc and Kp expressions, ICE tables for equilibrium concentration calculations, Le Chatelier's principle, relationship between Gibbs free energy and K. 2 timed FRQs. |
| Week 5 Apr 6 | Units 8 & 9: Acids and Bases + Electrochemistry | Ka/Kb calculations, pH and pOH from weak acid/base equilibria, buffer calculations using Henderson-Hasselbalch, titration curves and equivalence points, standard cell potentials from reduction potentials, Nernst equation, electrolysis and Faraday's law. Take Practice Exam 1 at end of week under real timing (60 MCQ + 7 FRQ). |
| Week 6 Apr 13 | Math-heavy calculation intensive | Drill every quantitative problem type you missed on Practice Exam 1. Run through: stoichiometry (5 problems), gas laws including ideal and real (5), pH and buffer calculations (5), Gibbs and equilibrium (5), Nernst equation (3), electrolysis charge calculations (3). Show full unit analysis on every problem. |
| Week 7 Apr 20 | Practice Exam 2 + FRQ intensive | Take Practice Exam 2. Compare raw score to week 5. Write 3 long FRQs under timed conditions (25 min each). Focus on explaining mechanisms clearly, connecting concepts across units (e.g., how IMFs affect boiling point, which affects vapor pressure, which connects to phase diagrams). |
| Week 8 Apr 27 | Sharpen & rest | Short spaced review across all 9 units. 2 FRQs per day Mon-Thu targeting your two weakest units. Review the formula reference sheet so nothing surprises you. Fri-Sat: flashcards on key reaction types and periodic trends, then rest. May 5 is exam day. |

Generate My Schedule FreeUnit weights on the AP Chemistry exam
The College Board publishes approximate weight ranges for each unit. Unit 3 alone can account for nearly a quarter of your score, so it deserves disproportionate time early.
- Unit 1 (Atomic Structure and Properties): 7-9%
- Unit 2 (Molecular and Ionic Compound Structure and Properties): 7-9%
- Unit 3 (Intermolecular Forces and Properties): 18-22% (highest weight, front-load this)
- Unit 4 (Chemical Reactions): 7-9%
- Unit 5 (Kinetics): 7-9%
- Unit 6 (Thermodynamics): 7-9%
- Unit 7 (Equilibrium): 7-9%
- Unit 8 (Acids and Bases): 11-15% (second highest, prioritize Ka/Kb and buffers)
- Unit 9 (Applications of Thermodynamics / Electrochemistry): 7-9%
What most AP Chemistry students get wrong
They memorize periodic trends without understanding the underlying reason. The AP exam does not ask you to recall that atomic radius decreases across a period. It asks you to explain why, using nuclear charge and electron shielding. If you can only state the trend, you will miss the explanation points on FRQs.
They avoid the math. AP Chemistry is one of the most quantitative AP exams. Stoichiometry, pH calculations, Gibbs free energy, cell potentials, Nernst equation, and Faraday's law all require setting up and solving calculations under time pressure. Students who spend most of their prep reading notes instead of working problems are not prepared for exam day. Every study session should include calculation problems.
They under-prepare for the long FRQs. The three long FRQs each require you to explain mechanisms, justify trends, and connect concepts across multiple units, not just plug numbers into formulas. Practice writing out complete responses with full reasoning. A correct numerical answer with no explanation earns partial credit at best.
They misunderstand entropy. Many students still think entropy means disorder. The more precise and more testable definition is that entropy measures the number of accessible microstates for a system. This matters when the exam asks you to justify the sign of delta-S for a reaction: focus on the number of particles in gas phase, not vague notions of messiness.
They skip phase diagrams and heating/cooling curves. These topics live in Unit 3, the highest-weight unit, and they appear on almost every exam. A heating curve tests whether you understand that temperature does not change during a phase transition. A phase diagram tests whether you can identify the triple point, critical point, and which direction pressure or temperature changes shift the phase. Both are learnable in a single study session and high-yield.
