Users can find, preview, and download past Chinese Physics Olympiad (全国中学生物理竞赛) problem sets & solutions as PDFs, organized by year, level, and topic.
Before diving into the PDFs, it is crucial to understand the ecosystem. The Chinese Physics Olympiad (全国中学生物理竞赛) is not a single exam but a multi-layered pyramid: Chinese Physics Olympiad Problems Pdf
A typical Western physics contest problem often relies on a single "trick" or insight. You solve it, you feel clever, and you move on. CPhO problems, however, are architectural. Feature: CPhO Problem PDF Explorer 1
A typical CPhO Problems PDF is structured in two distinct phases, mirroring the competition itself. The first part, the "Preliminary" or "Competition" round, presents a series of short-answer and calculation problems designed to be solved in three hours. These problems cover classical mechanics, electromagnetism, thermodynamics, and optics, but with a twist: they require a fluency in calculus and vector analysis that goes far beyond the typical AP or A-level curriculum. For example, a problem might ask for the moment of inertia of a non-uniform rod or the electric field of a charge distribution using Gauss’s law in differential form. The second part, the "Experimental" round, is what truly distinguishes the CPhO. The PDF often includes detailed descriptions of real-world setups—measuring the Young's modulus of a steel wire using optical levers or determining the unknown capacitance of a circuit. The challenge is not just in performing calculations but in designing the experimental procedure itself, analyzing systematic errors, and graphing data with precision.

Chinese students solve thousands of problems. The famous “Physics Olympiad Problem Sets” are organized by difficulty: Junior High, High School Preliminary, Provincial (Division), National Final, and IPhO selection camp. Each PDF typically contains 5–20 years of past exams with official solutions.
CPhO problems are designed to push the boundaries of high school and introductory undergraduate physics. They frequently require: Complex Modeling
