two minutes of A problem, that's really fast, how do you guys did that? Reading problem description would spend me about two minutes. Be polite to me :)

    Just solve 50+ or 100+ extremely easy problems and you will get to solve div.2 A in less than five minutes in average ... I would suggest opening problem set of codeforces and sorting problems by number of members who solved it and solve the first 1 or 2 pages ... This would develop your speed enormously with easy problems.

      While what YellowNextYear said should work, I don't see the point in training stuff you already know. You solved Div2-A in 9 minutes, the difference between that and 2 minutes is negligible in my opinion.

      Focusing on trying to solve more problems is a better strategy than trying to solve the first two faster, at least until time becomes an issue (as you had 1h30 to solve C, I don't think that's the case). Sorting by number of members who solved it is a good idea, then pick the range of problems you take around 30 minutes to 1 hour to solve, and you should improve from there.
