As the title says, I don't feel like I've improved that much since summer despite practicing harder than before. I don't even know what to practice anymore. When solving Codeforces problems I either come up with the solution really quickly or can't come up with any ideas no matter how much time I spend on it, also I don't feel like I improve after practicing Codeforces problems. Sometimes I struggle with 1400 problems and sometimes I solve 1700/1800 problems easily. I don't feel like my rating is an accurate representation of my skill and don't know if it should be lower or higher, and because of that I don't know which problems to practice, every time I pick some problem it's either too easy or too hard(or I just give up to quickly idk). Was anyone else in a similar situation before, if so how did you get out of it? Any help is appreciated, thanks in advance!
