How to practice for Chemistry
- Show units and significant steps in calculations. Free-response points often hinge on a correct setup as much as the number.
- Practice explanations at the particle level (why, in terms of intermolecular forces, structure or energy), since many points ask you to justify a claim.
- Mix long (10-point) and short (4-point) questions in timed sets so your pacing matches the exam.
Then grade what you wrote (how to grade your own FRQs) and log what you miss (turn missed questions into a study plan).
