learn fft
then do 1200-1400 range problems
You should practice some problems that require thinking and learn some basic and useful algorithms like binary-search, the easy part of greedy and dynamic programming, then you can work out 3 problems in Div2 and more in Div3 and Div4.

Look at this guy's blog and evaluation of others, he is just a cheater! He always says that he will never use Codeforces again and ask for ways to improve himself, it sounds good, right? But actually he cheated again and again in the contests and ask for some stupid questions that is already answered in 'Help'.
start giving contests rather than blabbering
ahh another indian. you dont wanna get exposed so you are too much concerned about your fellow cheaters too right?
