comment High school mathematical research
*to be honest I'm very skeptical about the article I put in the link above. (See physics.stackexchange.com/questions/28931/…) I don't know whether any high school student has actually solved any open problem before, but basically my point is that as a high school student you really shouldn't be looking for open problems to solve. (as far as I know)

comment High school mathematical research
You need to be at like Master's degree level (after undergraduate college) to tackle open problems. You really shouldn't look for high school level open problems, I don't think any exist. However, there have been exceptional high school student(s) who solved open problems in high school. (See educationviews.org/…)
