Is there a disability advocate at your school? If not, I know there are some websites for persons on the spectrum. They tend to be populated with the very young who are trying it all on. But there are other people on those boards who have been dealing with this stuff all their lives and already blazed the kind of path you need. Maybe if you try posting on one of them you might find someone who would share how they got what they needed?
But yeah, you need the appropriate documentation, and then you need some of that software that reads printed matter to you. You may get tired of the repetition, but at least you'll be able to hear it instead of having to read it. Unfortunately, my experience with higher ed is that there's a boatload of repetition. It can be just numbing. I know someone who takes a voice recorder with her, sometimes, to class. Amazingly, the Uni here gave her one. (Getting the same in the States you have to do yourself, as the legislation dealing with disability issues pretty much leaves you hanging once you leave high school.)
If you have trouble with the typing, there's Dragon software, which is pretty good, once you get it trained to your voice. Keep at it, get that doctor behind you.
