yes, just look at each puzzle until you find a win. Set up a board and place all the pieces on it, then record what you think for each move and play it out on the board until you've fully solved the puzzle. This is a fool-proof (unless you get lazy) way to solve puzzles, so... might take a couple hours but once you do it once it's easier the next time...
or you could just take free stuff and boom, 20+...
I've been playing chess for 6 years (used Chess.com for 2 of those years) and I can't even get 10 on puzzle rush! Can you please help me?
