Hi everyone, As a beginner, how many questions should I up-solve after contest? Recently I have participated in Div2 contest and not able to solve any questions. Sometimes I am able to solve A but sometimes I struggle for two hour for a A level question during the contest... I believe that up-solving is much required.. But I couldn't figure out that how many questions should I upsolve after the contest? Can anyone tell me about that?

Thanks in Advance....
