We've redesigned, updated, rerouted and regrouped the library for better discoverability and a better flow. You can visit the new documentation here.

These are the .

A PDF with just the answer keys is of limited use. The real value lies in the step-by-step derivations, which reveal the problem-solving methodology.

The physics community on AoPS frequently shares translated threads, crowdsourced LaTeX PDFs, and step-by-step solution guides for recent CPhO exams.

Do not attempt CPHO Semi-Final problems without a firm grasp of multivariable calculus, Taylor series approximations, and ordinary differential equations.

Because the Chinese national team consistently dominates the IPhO, training with the materials they use gives you a distinct competitive edge. If you can confidently navigate a CPhO Finals PDF, competitions like the USAPhO, British Physics Olympiad (BPhO), or the IPhO itself will feel significantly more manageable.

The goal is to learn how to approach a problem, not just to find the final numerical answer.
