Hello Codeforces

Nowadays I am preparing for ACM-ICPC regional finals, I became master 2 months ago, but I think its by luck, because I have solved a lot of problems(almost 2500) and I know typical problems, therefore I solve them very fast(speedforces), because I have experience with them.

What I want to know how to go further, I think its hardest level to become red coder from master, what strategy should I use, I have seen a lot of people who stuck at orange for many years and some people who are becoming red coder from orange in 6 months.

I have set up my target as becoming International Master till Regional Finals(April 2021) and I believe in the last 2 years of my study I will go to ICPC Finals

Thank you, GL & HF
