I have been doing Competitive Programming for a while now and have solved a good number of problems (mostly 800–1200 rated ones). I try to be consistent, and I’ve also participated in 25+ contests, but I still find myself stuck in the newbie range. Sometimes I get stuck on problems even after solving similar ones before, and during contests(div-2), I am not able to solve B problem regularly. I really want to improve and reach Pupil soon, but I feel I might be missing something important in my learning process.

What should I do to get out of newbie and improve my ratings?
