I think it is fair that some people get extra time as they may not even be able to produce the content of the exam within the period of time given, if the time given in exams was more sparing then a low handwriting or cognition or reading speed would be a less significant disadvantage. As for me i recieve extra time for handwritting speed- which is a genuine issue for me as i damaged my wrist a while back and it becomes agravated when i write quickly, and for thought processing speed, in this comment alone i think i have spent about 40 minutes thinking about what i wanted to say, this meaning i would have nothing to present in an ordanairy exam. I have never finnished a test without extra time, therefore if i was to be marked, i dont know what would happen with half the paper missing. Last year in the core science GCSE exams while my school send department was still applying for extra time, i only completed 2/3 of the paper, doing only 2 questions on the physics section at the back. I thought i failed, because i didnt even get a chance to pen the back questions which from a glance i knew how to do. Luckily i must have gotten nearly 100% on the chemistry and biology so inspite of that i got an A. However it was really frustrating because i put a lot of effort in and i just wanted to be tested fairly, whatever that meant, and i do not think not even having a chance to get to the back questions was fair because i could do them, i was held back by issues in translating thoughts onto the paper.
There is nothing wrong with an A, its what i wanted, but the stress of going home without doing any physics made me terrified, i could not see how i could come out of it ok and i felt failed by the system.
In a workplace somone like me wouldnt mind doing work at home, inorder to catch up on written pieces, if thats what it takes, i hope somone would value the quality of work too, not just the speed at which you can through it out. i also gather work is mainly done on computers these days, which reduces time issues for most extra- time students.
