In the resources section, mention official Cuban education websites or collections like "Colección Olimpiadas de Matemática Cuba" if that's a real thing. Also, recommend other resources like books compiled from past olimpiadas or PDFs available online through Cuban mathematical societies or international platforms like arXiv or problem-solving blogs.
For problem types, maybe give an example problem from a past CMO. I need to create a hypothetical example if I don't have a real one. Wait, but if the report is about the CMO in general, maybe not providing a specific problem is better unless I can ensure accuracy. Alternatively, refer to types of problems without giving exact solutions. Or perhaps mention that the problems are similar to international olympiads in style. cuban mathematical olympiads pdf
For international competitions, note that Cuban teams have won medals at the IMO, perhaps mentioning the years when they started participating internationally and their performance over the years. Maybe some Cuban students have won individual gold, silver, or bronze medals. In the resources section, mention official Cuban education
