I used to tutor for USACO a couple years ago, and I think the majority of my students were pretty successful. No, I don't anymore, and I don't have plans to continue.
However, since it'd otherwise go to waste, here is an early Christmas present of the list I'd built up of some of my favorite problems that I'd give and go over in sessions. It is primarily for gold+ contenders. Enjoy!

Hi! Thanks for the amazing work. Will gold problems be suitable for me?
Bedoo sounds like a coincidence
