tech knockout you don't just have to prove you have the disability, but you have to prove it has affected you adversly, ie, get teachers/prinicple to write a statement saying you have trouble hearing & therefore concentrating and keeping up in class, it is difficult for you to participate in class discussions because the background noise makes it difficult to hear ppl talking ect. ect. ect.
I'm not sure if they would accept it because they generally only accept people with two eas categories (or one reaaallly bad one) as someone said. Also, you cannot claim EAS for lost study time (ie if you broke your leg a week before the exams, but was still able to show up) so you would have to prove that your ear probs had led to a real learning disability...
I got in on EAS for financial harship & excessive family responsibilities saying it affected me through worry about finances, not being able to buy textbooks and not being able to study as hard because I had to work all the time (note: this is different to lost study time as I mentioned above because it was all through yr 11 & 12, not just before exams or whatever)
moral to this post: how it has affected you is more important to them than the disadvantage/disability (which is why they tend to let ppl in on bullshit stuff like they are stressed or thier father beats them up)
