I see tutor as someone that teaches. By definition, when referring to "tutors" they are not learning, they are teaching. That's why I said they're here to share their knowledge.

A "scholar" is much like a student. So they're here to learn, and share their knowledge.

If it were up to me I'd remove Tutor and Knight, and maybe Master and Guru, because I don't think there's much of a need for them. It's over-complicating a simple thing.
