Any tips?

I ain't a fide rated but Ig I should get one.
Just do puzzles as much as u can also perfect your repertoires that's it and also read endgame books or do the endgame puzzles.

i am 1800 fide and i have dropped a lot lately and i would suggest to not look at the ratings too much and just focus on trying to improve your game by learning from your mistakes and also don't try to strain yourself too much during the game by thinking about the rating, just try to play your best game.Hope that helps
I am a 13 years old boy with a FIDE rating of 1605. I got my FIDE rating in October. However, I think I am in a big slump since my rating decreased a lot these days.
Are there any good players who has a FIDE rating above 1800 to give me some advice?
Thanks.
