Hello, I was not sure quite where to post this but settles on here. I am a 15 year old and I am having an issue. I desperately want to train for the IMO and I know what material I need to cover and then ill do past problems and so forth. The books I intend to use to learn the material are G H Hardy for number theory, "a course in combinatorics" and some more. Are those appropriate? However, I also want to carry on learning undergraduate material like ODE, analysis and linear algebra etc. will I be able to do both of these? I can work very long and I intend to. There is one lost query. It has been a lifelong dream to go to trinity college cambridge an I can't imagine not going there. This causes a lot of stress because I know I have to prove myself to get in. It is not the reason for me to et to IMO, that's because I like maths, but I know it COULD be a decider. I also want to go to IOI. Will it be possible for me to train for both of these and learn undergrad material as well? How do I deal with the stress issue and the anxiety of not getting into cambridge? Note: I know I can easily get 3 A* at a level and get S, S on STEP as I have done so consistently on papers as am taking it in winter. Also, please don't tell me to stop looking so far ahead. I just want to get on with what I love doing. The reason I am having these issue is apparently because of my aspergers so please don't comment in sarcastic or unhelpful ways.
