> college here gives students with ADHD double time on exams

No offence, but this is a ridiculous thing to get worked up about. Various neurological conditions exhibit in people just being “slow” in exams. No one ever diagnosed me with anything (probably too long ago), but teachers somehow understood that I was one of these and gave me extra time on exams.

I didn’t want it (who wants to be in an exam a minute longer than required!). But I did need it through high school. In university I was able to complete in time (mostly); I suspect because I had practiced doing exams so much by then that I’d figured out how to optimise for time (maybe everyone knows this and I was just very slow to learn it?).

I’m someone who excelled academically, and it was an important part of my identity at that time. And I do remember exams (before teachers gave me more time) where I’d get a lower grade as I’d only completed 70%. It was incredibly painful; I knew the material, if only I could get it down on paper in time! (I’ve also been an incredibly slow writer). Extra time for someone who struggles to complete on time isn’t cheating - it’s allowing people to demonstrate what they can do.
