I am a 3*. I have been one for 3 months. I became a 3 star in my third contest but ever since I have stagnated in the same range for around 10 contests, but I feel like I have really grown, practiced and learnt a lot of new things in this time period.
My problem is definitely consistency. In some contests, I solve both 4* and 5* star problems that result in +60 or so then in few contests I get stuck in some 1750 problem that again decreases my rating by quite a few. This just keeps happening.
If I want to practice, a lot of problems are very old and not even from starters or with same pattern. Is there some way to practice high quality problems like cfladders or many websites for codeforces?
