Chinese problem writers love perturbation theory. They will give a system with a tiny dimensionless parameter (e.g., $m/M = 10^-3$) and ask for the first-order correction to the frequency. This trains the mind for real physics, where exact solutions are rare. chinese+physics+olympiad+problems+pdf+top

CPhO problems often mirror advanced Soviet-era problems and theoretical physics models.

The best source for raw, recent PDFs is not a bookstore, but a question bank.
