I became pupil. I'm going to talk how I became pupil. At first I couldn't focus problems in contests, every div2 B was hard for me. My goal was reaching 1000 rating. After this my next goal was 1200. It was hard for me to reach 1000. In Good Bye 2025 I became 1036 rating. If you go to my profile and check contests, you will saw that I reach 1200 so fast after 1000. I realized that, looking at standings make people feel discourage, so I planned to not look at standings. It didn't take much time to understand that reading statement wrong is waste of time, so I read statements more carefully. Sometimes I cannot solve easy problems in contests, that's also discourages me but I learned fast that if you cannot solve a problem, don't get discouraged and go to next problem. If you look my last contest you will saw that I write problem B first then problem A. I tought problem A is hard, so I looked problem B and I found a solution, then I solved. I looked at to problem A then, but I saw it's so easy, and I solved this too. These are all tactics that can improve your contest performance.
