Hmm well most of these seem to be coming from a instructor point of view so I'll put some from a student point of view.
When you and the chosen instructor who is working with you have been doing nothing but reviewing the form you're working, and you get the part you know down so well that he can't find anything to correct yet he still doens't teach you anything new. there's a few instructors at the Academy who do that, and sometimes I'll be paried up with themm alot, and it can take months just to learn a couple of moves because of it, which honestly is way too long. Though the review helps, adding on so I can review that as well helps also.
