Hi guys! I'm wondering about what is the best way to prepare myself for IOI. I've been to IOI, but I seek better results. For my preparation, I'm solving tasks in oichecklist, currently USACO and JOI Spring Camp 2018-2023. Do you have any suggestions of what other tasks I could focus on solving? Thanks beforehand.

It would be very helpful if you could provide me with some kind of documentation.

Thanks in advance!
