I'll start and Karen can finish.
What happens is that typically a person with a perceptual disability ends up taking longer at university because they're waiting for their books. They often take part-time classes. It's not disability-related all the time, it's often simply resource-related. So it takes longer to get through university. It's more demanding. Their marks aren't as high because they've started reading the material in October and everybody else started in September, so it creates an uneven playing field. The more complicated it becomes to produce alternate formats—and technical protection measures certainly complicate things—the longer it takes to get books to kids. Whether they be books, course packs, or whatever, get them to kids the same time as their non-disabled peers are getting them.
