I'm an undergraduate student and recently I've been trying to find a private tutor to help me further expand my knowledge (outside of a scope of my courses). I've discovered one of the TAs advertises themselves as a private tutor. Would it be ethically wrong to hire them? Are there any potential issues/conflicts of interests?
As far as I know there is nothing strictly forbidding it in the university codes and I would love hiring them - I'm quite picky when it comes to the teaching style and in case of the TA in question I already know it'd be a great fit.
