Hello codeforces!
About 10 months ago,I reached Expert after two years of practicing (well , I wasn't really practicing then )
But since being an expert , I nearly didn't miss a contest unless I wasn't able to participate , but I'm still going up and down in expert (and sometimes specialist too) , and I reached a rate more than 1800 only once, although I have some contests with a master performance.
And unfortunately, I accepted Ali_ZaiBug 's challenge that if i don't reach purple before the first of November(which is very soon) , he will upload a post on facebook laughing on me ):
Well, I don't really care about the post, but I want to reach purple before 2023.
So can I have some advices please ?
Thanks !
