I am trying to independently learn mathematics at an upper-level undergraduate and first year grad student level. It's mostly linear algebra and statistics. The textbooks that I'm reading are quickly becoming more proof-based than I've previously experienced.
Occasionally, I feel that I need someone to just bounce an idea off or to ask for some clarification. I submit questions to stackexchange sometimes, but the format of the site understandably discourages the vague and ill-formed questions that I often have.
A separate motivation is to have someone who holds me accountable for making some progress and additionally can direct my studying.
Do you have suggestions for how to find someone who could help me? Should I offer to pay a math grad student at the local university? Should I try to find a willing professor? Other suggestions?
