Hello sirs/madams/others,

I have recently noticed that I often struggle on B problems in division 2 contests I participate in. Moreover, they're often the last problem I manage to solve. Usually I read the problem incorrectly or miss a crucial observation and am thus unable to solve it. Do you guys have any tips I can use to overcome this obstacle?

UPDATE: So guys, this contest (edu 85) I tried to conquer this and solve B first, but it took too long and I didn't have enough time to work out the solution for F, the next easiest.

How do I get better?

Sincerely, praise kaunta
