Hello! I am preparing for International Physics Olympiad and I recently saw your website and used the Chinese Physics materials. They are very good. I wanted to know if you could send me the National Chinese Team Training Tests (国家集训队试题)? It will be really useful. I have already solved the CPhO problems and the questions from the 国家集训队试题 of the year 2013. I need the 国家集训队试题 after 2013.. Thank you!
