I'm studying at the moment, a computing degree, and quite a lot of the material I'm given is multimedia. So where your average student is being asked to do maybe 15 hours of work a week, by the time I've found some sighted assistant to come and explain to me what I'm supposed to be looking at on a screen or to operate multimedia content that I can't do for myself, I've added another 5 or 10 hours onto my working week. The difference in not being able to access multimedia content is quite extraordinary from my point of view. It's the difference between a Saturday working or more often than not a Saturday and a Sunday working through the weekend to get my studying done.
