Read editorial to task that you cant solve (Div2 C), then solve it and try to keep in mind something about the solution to use it in other tasks.

Been there, A , B are moslty implementation, for C you need to know some basic algorithms and data structure like binary search, DFS, BFS, some Number Theory tricks ... I suggest you focus on A & B for now while learning some basic algorithms .

    learning is necessary but just learning algorithms is not enough.

    you have to first learn this algorithms and after that practice them a lot(for this you can use CF algorithm tags)

This Post for I_love_Hoang_Yen maybe help u.

+= don't say that u "can't do C or more" , always open C and the higher problems , Read them and do your best.if they about some algo. go and learn it. and always read the editorial/other's solutions. this will help you.

and always keep going :)

Pick a div2 C you think you can't do. Then set a timer for 1 hour. Spend the hour trying to solve the problem by yourself. If you still have no idea how to solve it after an hour look at the editorial.

Solve C problems of last 100-150 contests and BOOM!! You will hardly miss C. Starting Contest With problem C is a good approach.
