    I suggest solving Codeforces Div. 2, x ladder instead of rating ladder. Note that you have to create an account and your account should be verified to use the ladder

The thing is, there is no "bunch of problem list for solving cf div2 A, B, C during contest time." just like there is no magic set of questions to do for aceing every exam (let me know if you find the latter).

You just got to learn to be creative and have a good amount of standard algorithms/problem solving techniques in your head. Thereafter speed determines the result. Of course, there are certain "topics" that appear quite often in div 2 A, B, C and some that never get used at all. What is this list? I'll leave this as an exercise for you.

After 3 contests, I have finally reached blue. I would recommend reading online tutorials

To become blue, you need to learn a programming language.

Perhaps, virtual contests are the best ways!

I can help you become blue if you're purple.

    Btw, why would you intentionally decline to blue? (Div 2, 554). Just curious.

    You were 'slow but determined' while increasing your rating but seems like Google made you pretty fast in decreasing your rating xD
