A better OI Checklist
Some of you might remember the old OI Checklist from years ago. It was a great tool for its time, but it’s no longer updated, missing recent contests, closed source, and lacking a lot of features competitive programmers now expect.
This is the modern, actively maintained, open-source successor.
It already supports dozens of Olympiads— from IOI, APIO, CEOI, BOI, EGOI to USACO, NOI.sg, and even Google Kick Start— and it’s built to be easily extended.
What are you waiting for? Go and try it now!
