I do 3 puzzles a day

Helle Epeop,
Personally, I would do a lot of puzzles. At your level it’s just pattern recognition(basically what you train with puzzles),learn a simple opening, know some endgame knowledge and you’re good to go.
Don't focus on the number of puzzles you do, more on the time you spend solving them. When you do puzzles, make sure you try to solve the whole puzzle in your head before making the first move. Doing 2 puzzles well in 15 minutes is going to always be more helpful then doing 10 puzzles poorly in the same time.
I'm rated 950 Rapid on chess.com and my question is how much puzzles should I do a day for improving my tactics?
