I am shown 79+ in Educational Codeforces Round 108 (Rated for Div. 2) but i get only 50+ after actual rating changes happen.
Am i practicing in the right way? At least for the last 6-7 months I am trying to get better , I generally solve problems around 1500-1900(have solved 100+ problems within this range) , I try to up solve upto D or E , I try to do it without the help of editorial. I know most of the algorithms needed to solve upto D or E. But I still can't reach expert? How do I practice more efficiently? And codeforces is notthe only platform where i practice .
