I have been doing USACO guide the bronze level fro some time and I finished it, yet when I get to a new USACO problem I have no clue how to solve it, so for anyone who is pro, how did you learn, what resources/ courses did you do?
I don’t know what to tell you, I’m not sure how you “finished” the guide with no problem solving skills, unless you gave up too early and read a bunch of editorials. I would advise holding off on reading the editorials until you have a solution or have spent a several hours on a problem and simply do more problems (if you ran out do some easy cf problems, start at around 800 and work your way up, these problems should be fairly trivial).
