As with every single thread I have ever read on this site which deals, even tangentially, with matters pertaining to disability, the offensive, ignorant ableist commenters are out in force.
I know this may cause some commenters to faint with outrage, but I not only had a private room in which to complete my GCSE exams but also had unlimited time. I am completely blind, have been since birth. When I did my GCSEs there was no provision made for submitting exam transcripts electronically and the exam board did not have the ability to process papers submitted in braille so, while the papers were provided to me in braille, I had to dictate my answers to a scribe. I am not sure if anyone here has ever had to dictate an essay on the agrarian revolution, a Latin to English translation of Caesar's war diaries or describe a diagram of the photosynthesis process or the plotting of information on various types of graphs, but I certainly did all these things and many more during my GCSEs. I would like some of the posters on this thread to imagine how hard it is to compose an essay, for example, when one cannot simply go back and read what one has just written. If I lost my train of thought or wanted to work out the best way of composing the next section of the essay I had to ask my scribe to re-read what I had just written. This was a long and exhausting process for both my scribe and I. Without significant amounts of extra time and a private room this would have been impossible. I could not have shared a room with others since I was having to dictate all my answers. I received 7 A* and 2 A grades in my GCSEs. Perhaps some posters might say I did not deserve them because of the accommodations that were made for me, I don't feel that way and I would hope that nobody with any sense or compassion would either.
When I came to take my A-levels the situation had improved significantly as I was able to write my answers on a laptop, loaded with adaptive technology, and submit an electronic transcript. I still required extra time as it generally took more time to read back over a transcript with a screen reader than it does to do the same visually, especially if needing to correct spelling, but I no longer required an indefinite period of extra time. I'm sure there are posters on this thread who have hard time accepting that kids can submit papers electronically. All I can say is that I am glad that my employer did not see the accommodations made for me during my exams as a reason not to employ me, as some of the charmers on this thread have said they would do themselves if confronted with a candidate in my position.
