I cannot say that I can solve 2 problems in an div2 contest because I have only given 17 rated contests. I am struggling in 1100 rated problems during the contests. My only priority right now is to be efficient at 1100 to 1200 rated problems. I sincerely don't understand what to learn, why to learn, How to Learn right now. The things that I have learnt till now is some observational thinking(includes constructive algorithms and some number theory concepts), some bitmasks, very little ideas about binary search. I need some ideas on what to learn next, why to learn that, how to practice, where to practice(If Codeforces then I get lost inside the Problemset and couldn't able to find a way out. In fact filtering problems also doesn't help me either). I desperately need a way out. If anyone can suggest some gym(like some groups) will be helpful to proceed.
