Candidate Masters

I'm not even close to getting to that point, but I want to know so I know what I'm shooting for, you know?
You'd be shooting for a 2200 FIDE rating. This means going to tournaments and regularly scoring roughly 3 out of 4 against 2000 rated players, roughly 2 out of 4 against 2200 rated players, and roughly 1 out of 4 against 2400 rated players.
More generally this means you'll have studied every aspect of the game seriously at one point or another. Working hard (taking notes, memorization, multiple re reading, personal analysis, etc) though one book on each of the following is a good start: openings, strategy, endgames, tactics, annotated game collection.

norms.
You don't need norms for the FIDE CM title. It only requires getting a published or interim rating >=2200. As far as I can tell from reading through the regulations, it doesn't appear anything else has to be done. The same appears to be true of WFM, WCM and FM titles.

Let's say you get good enough at chess that you think you could earn the Candidate Master title, what do you have to do to be a Candidate Master? I know you need a certain FIDE rating and you have to pay a fee, but what else is required to officially have the title? I'm not even close to getting to that point, but I want to know so I know what I'm shooting for, you know?
