Hello codeforces!

I recently began to notice that my rating began to drop significantly. I couldn't even solve 2 problems from yesterday's Division 2, although the number of people who solved B or C exceeded 18,000!

This is already the 4th contest where I have lost my rating. This won't do anymore. My goal is to reach a rating of 1200 before the summer.

Can anyone tell me what topics, and in general, what should I do in order to reach a pupil in such a time?

Thank you in advance and wish you all the BEST!

Plus, I want to continue blogging about my progress in CP:)
