Hello guys, I am doing cp for the past 1.5 years, but my rating on codechef is fluctuating between upper 3 star(1770<x<1850). I participated in a rated contest on codechef and again fell to 3 star from 4 star. I pretty much participate in each and every contest held here on codechef(rated-unrated), regular of cf(lower specialist there),hackerearth and anywhere I find any ongoing contest(atcoder,hackerrank). Is it that I am wasting my time by doing these contests while I am not showing any commendable improvement,and also in which I could study new things or am I going on the right path? Just need this small advise. Thank you.
