I have discovered the custom puzzles recently. There you can grind a specific tactic until it comes automatically for you. Without knowing good tactics you can't reach the 80th percentile (1000) on chess.com
Your puzzle rating is 563 and mine is 1800+, so play 30min Rapid and do a LOT of puzzles .
Ive been playing chess for 4 or 5 month and i want to reach 1000 elo and im still in 400 elo how to do this
