A method/tool to find weaknesses in my games.

By weaknesses I mean things like poor endgame play, surrendering the center too often, etc. It would be better if you can suggest some ways to find weaknesses which don't consume much time (max 20 minutes) because I will have board exams in this academic year, so, there isn't gonna be much time for chess.

Try solving puzzles!
After you solve many puzzles , go to puzzle Dashboard and it show your weakness , strength etc.

That's what I call commitment!

A tool: Your brain!
A method: Trial and error - someday you will succeed!

I also have board exams this session, but you first need to focus on study and not chess.
Else, you wouldn't be able to perform well in exams.

You can use your chess insights to see what phase of the game your average centipawn loss or opportunism (how often you punish opponent's blunders) is highest. If you have a high ACPL or low opportunism in the endgame, you should probably study the endgame more. You should also analyse your games with the computer after you play and see where you made blunders and why. Sometimes it is due to a missed tactic, or a strategic mistake, e.g. leaving your King in the centre, keeping your pieces inactive, etc.
Lichess insights is nice, in fact I tried in the past but isn't much helpful, anyways thanks for the suggestions.

That's why I want methods that are not too much time consuming.

The king Clash told you how.

Just take the ACPL with a grain of salt. If you play out drawn endgames it will be too low, if you end in flagging mode each game it will also be off the charts and lose relevance.

But it’s the only way how you can analyze quickly (not in 20min tho unless you have done it before). And then you know what to study and analyze, but you didn’t do it yet!

—> if you wanna use your time efficiently to try and figure out your weaknesses, analyze your games while the memories are fresh. Or just study something, doesn’t really matter what (important thing is not to waste time with a study plan when you only have 20 min anyways). Probably rook or pawn endgames will help the most: they come up all the time and they are hard to calculate and more often than not there might be time trouble plus there’s some reoccurring positions that are superhard to convert until someone shows you how. Your rating is close to the point where exchange sac / pawn sac / piece sac becomes more relevant, but you usually put those in the context of a game to see how the masters maneuvered their pieces and applied pressure to set them up, not really something you can do in 20 min even if you find a thematic puzzle study.

Study > analyze > play > procrastinate trying to make plans with such little time

Edit: Also i think puzzles are useless when you have 20 min, maybe some runs of puzzle storm, but I doubt the very easy tactics will boost a 2k+ player. It might be good to keep some board vision when you don’t have time to play. Personally I’d not go for something hectic when I wanna focus on education before or after.

I would advise you to study first bcz here, in very less time, you won't be able to analyse all the positions quickly (not meant by that you can't do it.....) But what I just mean is that whatever you'll learn in this little time, and when you will get in studies, due to big syllabus, you'll be fully engaged in it making you forget what you have learned now, so use your precious time and get into studies!

Better is to leave playing chess or make it rare habit for fun during breaks till boards unless you are a chess addict.
Else your situation would be like 'Dhobi ka kutta na ghar ka na ghat ka'! Hope you understood what I mean!
