I saw on Codeforces on regular basis ,that there are a lot of questions and answers about practicing and practicing more.
Although It is my opinion that the Educations Rounds are best for this, at least for people like me. They learns from it and the problems are very nice and intersesting.
There are many Educations Rounds will come and I will also try my best to keep this bolg update. Although if you want to genrates these links locally you can find the code on my github repo : https://github.com/adshin21/Codeforces-Contest-Selector-By-Div-s
