I spend almost 11 months training in codeforces and I didn't know any thing about problem solving before this time , and I have solved almost 270 problems but still gray coder , I think there is a problem in the way of my training ,

I need to tell me the techniques/Algorithms and the shortest path to be blue coder(in your opinion);

Thank you
