Adaptations for disabled students are really important and they really make a difference.
Story time! I was born disabled and acquired more disabilities as I grew, all of them undiagnosed until I was 24. Now at this point I was in uni, halfway through my degree with mediocre grades. Then I get the diagnoses and I'm officially disabled! So I ask for adaptations, mind you the bulk of adaptations is I do the exams in a different room than the other students.
Then for the first time I get really good grades in an exam, and get super anxious about it, what if they got it wrong?? So I'm talking this with my psychologist, and she's telling me "you studied a lot, and understood the subject" and I was like... "that doesn't mean I get a good grade", because that's how it had worked so far. Then she finally asks "did you have the knowledge for that grade", and I was like "yeah, obviously". And then it hit me, it was the first time I had a grade that was equivalent to the amount of knowledge I had on the subject. Just because I could do the exam in another room. Didn't study more, didn't know more, I just had adaptations for my disabilities.
Anyway, adaptations for disabled students are necessary
