I’ve been hovering around 1600 rating for some months now and some contests go well, while others stump me with problems I feel I really should be able to solve (often div 2 C). When I practice in virtual contests, I am able to get them pretty quickly though. I’ve thoroughly practiced 1500-1800 rated problems (without knowing topic) but still feel like there’s this glass barrier above me during most contests. Sometimes I rabbit-hole and miss “easy” ideas while a bunch of other people are able to solve it (like the last div 2 contest C problem). I’m not sure what exactly keeps holding me back, do you guys have any advice?
