Since no student is every really in a position to critique class, I'd just find another place to train. Best way to learn, imo, is to learn "chains" of moves: learn one technique and drill it til ya get it, then train a move that flows if the first one fails, and so on and so on...pretty soon you'll have a handful of moves that just flow naturally from any position will keep your opponent on defense.
I find it better to teach multiple moves that fit together from the same position so I think the way you're training may work out well for you.
Be sure to drill the moves and visualize the techniques as much as you can to help you retain the info.
Also when you roll, force yourself to try the combos (chains) in action even if it means your partner escapes or ends up tapping you while you're trying. A match in which you try a few of your new techniques with little success is more more productive than simply trying to not get tapped out.
Awesome advice Jeff. Thats kind of like what my trainer is constantly telling me. He says who cares if I get tapped in sparring practice, pick a move that is troubleing me and make it my goal to pull it off. Whether its a transition or whatever If I pull it off than in my mind I won.
