advice on practice

Правка en1, от purple_dreams, 2017-09-06 22:36:27

For a person who can do div 2 A and B comfortably and sometimes C, does practicing on D make sense. Will participating in div 1 virtual so that I start from div 2 C (div 1 A) help or should I stick to solving only C and D? Thank you.
