I am registered with the student disabilities center at my college. It is a good idea. It helps so much. I can get my textbooks in audio format since I have trouble focusing with reading. That and I get extra time for exams if I need them. The teachers are notified so you don't even have to explain anything to them each quarter. Some people get note taker's services. So another classmate takes notes for you.

Wishing you all the best on getting one less thing to worry about taken care of. You can get registered in the summer usually. I did it last summer, so that way you're all set before your classes even start.
