Hi there.
Ratings in puzzles and ratings on a given time control don't correlate as puzzles only relate to a very specific moment of the game.
I am rated over 2400 online (https://www.chess.com/member/ppandachess). I created a free course that will teach you a training plan to improve. Feel free to check it out: https://www.panda-chess.com/daily-improvement-plan
I hover between 700 - 800 rating on chess.com. Used to be stagnated at 600. So I tried doing the puzzles. They quickly became easy for me then a little hard and now easy again. I have worked over 3000 puzzles. People on here say do (tactics tactics tactics). However, I'm starting to see it's stupid advice. Getting good at tactics will NOT make you a better chess player. It only slightly improves board vision. Most of the tactics do not show up in game. It's pointless if you don't understand how to get into a position to allow tactics. I'm terrible at chess. Even if I reached a 3000 rating which I think I could accomplish, it will not translate to winning. Based on my experience puzzle rating also has 0% relevancy to your chess rating or ability. Anyone who tells you otherwise are just lazy coaches who don't actually teach or people who have no clue what they're talking about. This is just some advice for other beginners like me so they don't waste time unless they actually enjoy solving tactics. It's just a novelty when it comes to chess. I do they for fun now myself just to see how high I can get it just for laughs. Because it's a joke. I have even solved tactics out of books. They are to easy and teaches you nothing.
