What do you want the school to do for you? It sounds like they are giving you a lot of tools that might make learning easier for you, but if you have some specific idea about what is missing, it wouldn't hurt to ask for that as an accommodation as well.

Are there any study groups or tutoring on campus? Perhaps you could talk to the professor or some of your fellow students about forming a study group? Do you know how you learn best?
