I did some teacher assigned tutoring in my day, and really didn't mind it. I wouldn't necessarily see my kids enjoying it or getting any benefit from it, but for me it was kind of cool to get to know the kid who was probably held back and therefore basically a GIANT dude in 8th grade. As I recall he was just a very quiet sweet guy, maybe dyslexic, for all I knew at the time.
It certainly helped me understand that some folks are not doing badly because they are not trying. And it wasn't something I was forced to do, or asked to do a LOT of; that might have gone badly.
