I think extra time/any access arrangements are totally justified!
Personally I'm totally deaf in my right, have mild hearing loss in my left and have tinnitus. Yet 2 of my 3 a level choices as Spanish and french, for both of which listening in the exam is worth 25% of my overall grade!
We do our listening through head phones and can play it as many times as we like. For this reason I get 25% extra time and if i wanted a separate small quiet room. I was offered a live speaker so I could lip read but declined.
I get this time because when my tinnitus is bad I literally cannot hear/focus on anything and also it takes me time to adjust to new voices, even more so in foreign languages! Why should I be penalised for a condition I have no control over that could destroy 2 of my 3 grades.
Without the extra time to do my listening there is no way I would be on track for A*s in both languages. If you think I don't deserve that time, please explain how.
