Uh, so recently I've earned a spot to represent my country in the EJOI, now I really need help where to start practicing, like good practice, I know some algorithms decently like some graph algorithms, dp (I still struggle a bit on dp), greedy, dfs, bfs, recursion etc. I had exactly 235/400 points on my country's national Olympiad, and was 4th (which barely made me get a spot in the EJOI), I have around 3 months to do good practice, the Olympiad is on the 19th of September, so please if someone knows some good sources, videos or tasks to do, help out a pall! <3
I think you can try solving problems at beautiful platform and just solve a lot of problems in archive... Um_nik talked about ways of practicing CP here, main idea — solve problems and you'll get better at CP.
You can watch some videos made by Errichto here and some made by SecondThread here.
Thank you man! I really appreciate it!

Bosnia, it'd be great if I were to get a medal! :) Hope to go to the IOI next year too!
