wait for christmas and there will be option to change your color in codeforces ,it will take just a minute,don't waste 3-4 months for it.

Solve more problems,

According to me, having such kind of big targets often results in frustration. So those bigger targets should be divided into multiple smaller easily achievable targets, and then at a time, you should focus only on the next smaller target you planned. Also, solve problems that have ratings slightly higher than your current average rating.

If you actually had put in the effort the last 6 months you would have 9 months instead of 3!

Funnily enough that's how long i took from green to cm, which even then its a very conservative estimate because i didnt do that many contests at the time so my rating didnt converge.

I don't see a reason to make it that fast. Just enjoy CP and have some fun problemsolving, results will be there

From November 16th to December 22 of 2017, I went from 1407 to 2006 rating. I stated 8 points above pupil, but that's close enough I think, so yes, it's possible. You have to learn the topics you don't know, get fast, and perform well in a lot of rated contests that are close to each other.
