I do know that when I was in school, the disability center closed before classes would end for the day. So I would walk my blind friend to his last class and to the bus stop after, so he wouldn't have to count his steps, and risk getting on the wrong bus. It took him a full hour to walk the 15 minute walk without assistance. There were classes that he couldn't take because the center wasn't open late enough and those courses were only at night.
I was so impressed when my online program made sure all students were aware that they could still ask for accommodations for such things if needed. I attended both BYU and BYU-I and never once heard a professor mention to students that such resources were available.
