How to work through this paper

Sit the full paper timed at F=ma: 75 minutes · USAPhO: 3 hours, no calculator or notes.
Mark it against the official key before you look at any solution.
Rewrite complete solutions for every question you missed or guessed — writing it out is what moves the technique into recall.
Tag each loss by topic (Kinematics & dynamics, Energy & momentum, Rotation & oscillation, Electromagnetism, Thermodynamics & waves, Derivation technique).
Re-sit the same paper one week later and compare the time to your first attempt.
