Can't go higher than 1,500 😑

Plateauing is common at every level I think. My suggestion is to play a set amount of games a day so that all your focus is on those games, mix up your openings to get a fresh look at things, and practice puzzles and endgame drills. Good luck with your chess!

Don't mix up your openings. You should stick to the same few openings so you can learn from your mistakes and apply what you learn in future games. If you learn something from every game then you should make progress.

It can definitely help to review annotated games from Masters featuring the openings that you play so you are familiar with the typical middle game plans and ideas. You can either get a book or look up games on youtube.

Do tactics. They help A LOT. Keep up practice and tactics and you should be good. Later on when your ACTUALLY in the 1500's then you might want to get a coach

Well there was a time I thought I will never surpass 1000 rating, that was 3 years ago. My chess skills automatically kept on improving. Tactics played major role btw

Do you run the chess.com analysis on your games? If you do learn what mistakes you make. Then do exercises in the mistake areas. This might help you avoid future mistakes. You rating should improve if you eliminate these mistakes.

play daily chess, it rlly helps cuz u have a lot of time to assess all possibilities and tactics. also, get diamond membership to get access to lessons and more puzzles. @chamo2074, don't jump to conclusions, he could be talking about his USCF or FIDE rating.

a year ago I wouldve died to be a 1500. Wait, I was 1500 a year ago.
One and a HALF years ago I wouldve died to be a 1500.
