>Another big accommodation request is extra time on tests.

Yep. Speaking from experience, top colleges will given students with ADHD or similar conditions as much as double time or more on exams. One college I know of sends them to a disability services office to proctor it, in which they simply don't enforce time limits at all.

Coincidentally, there's an overwhelming number of students with ADHD compared to before these kinds of accommodations became standard.
