(At the time of writing this post I have 1542, Carrot shows +77 so I'll write in advance) After so much time I've reached 1600 and would like to share a couple of tips: if you want to specifically increase your rating, then understand what you're better at — coming up with constructive solutions or writing complex algorithms. If it's the former, then it's better to participate in lower divs, since divs 1-2 have many different algorithms, but this method only works up to 1600, beyond that you can't do without algorithms.

I would also like to ask for advice on creating problems and uploading them to polygon (since I want to start teaching and this skill is very necessary). At the moment I'm thinking of starting to grind more algorithms and reaching 1900, I would be happy to help with preparing or testing rounds.

thank you all for your attention and Mike for the wonderful codeforces

UPD: how do people find this post?
