Sometimes i find a high rating question very easy like G1 (https://codeforces.com/contest/1840/problem/G1) of round 878 div 3 but its rating is 2200. sometimes a low rating question like (https://codeforces.com/problemset/problem/1773/F) takes too much time . how they decide rating of question , on their own perspective or number of participate solve that question in contest. their question rating system is too much confusing.

I want know who added me as friend . If there is no way than i think this should be added.
