The report should be interesting, so maybe include some specific examples of problems or achievements. For instance, which years had notable results? Has Cuba won any medals in the IMO? Let me recall: Cuba has a strong tradition in mathematics education, and their students have done well in international competitions. In the IMO, Cuba started participating in the 1960s as well. Maybe mention some specific medals or famous Cuban mathematicians who were olympiad participants.
Maybe add a section on "Notable Cuban Mathematicians and Their Olympiad Backgrounds," if possible. For example, if any prominent Cuban mathematicians started in olympiads. However, without specific names, this might be speculative.
When discussing impact, perhaps mention how the CMO has contributed to developing mathematical talent, with some participants going on to become mathematicians, educators, or participating in research.
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.
