how to become FM?


Check out the 2nd link and look at FMs who play on chess.com
But also, OTB tournament play is different from online. You should go to tournaments before you'e close to FM because you'll have to get used to it, but also because playing strong players in tournament conditions is an important part of improving in general.

Agree with the above posts! Something else that might help: get some good books and actually work through them completely. And CM is the lowest Fide title yeah

What chess.com rating should I be before going for CM title?
