#I'm currently reviewing set theory but don't expect to limit myself to that

I'm looking to brush up on some reasonably advanced math concepts that may or may not end up being practically relevant to AI. At the moment I'm using MIT open courseware and some other hodgepodges, but does anyone have suggestions on forums or ways to hire (at least graduate level) tutors so I can get feedback on my practice proofs, guidance on unknown unknowns ect.

I did CS in school, and work in data science now so I'm fairly knowledgeable overall but in a way that is very patchwork relative to what I'm trying to do.
