How to win at Olympiads in Mathematics and Informatics?

Question

Programming

Good afternoon. I'm in the 10th grade.
How to win at Olympiads in Mathematics and Informatics? There are no problems with the school and city stages, but how to get to the final stage of the All-Russian Olympiad?
Obviously, you need to work hard for days, but what exactly to study and from what sources? How to practice?

Answer 1

No way
Just participate in the olympiads. Try. Again and again. And finally, you must really enjoy solving Olympiad problems, otherwise all your efforts will be useless.
From myself I will say that to solve programming competitions! = Good programming
I speak as a person who regularly participates in these.
Olympiads accustom to all anti-patterns, time limits do not allow finding a beautiful and elegant solution, they force you to copy-paste and write "if only it works."
Do not believe? Look at any solutions of the Olympiads - on codeforces.com for example.
It's hell and horror by all standards.
It is better to spend time on something really useful, for example, on your project, the development of which is only a joy.

Answer 2

Well, it's hardly worth it to swim and skydive every day. I suspect that it is necessary to solve the Olympiad problems of the past years, as much as possible. Participate in online competitions, topcoder, dvpion (lol) acmp.ru/index.asp?main=tasks
