I understand why people would be bothered about people having extra time, but it is not necessarily an advantage.
I've had special provisions since the beginning of the year, for anxiety related issues. When I had previously done exams in the hall, I felt overwhelmed, would panic and cry etc. Not only embarrassing, but completely distracting when I'm trying to sit an exam. So, I don't have extra time, rest breaks, I'm just seated in another room (by myself), or with a small group of people. Everyone at my school appears to need their provisions for whatever reason, and it's really frustrating having to justify your reasons alllllll the time.
