I'm not sure which paper we used, but I know it was from one of the company's that do them. The top was 88(Me) and then it went 87, I think 82, then it fell down, lots of people in the 70s. So the average for my school would have been about 70 odd. Quite depressing, heh.
I've been getting 90+%'s all year, so I'm hoping that being first in the year, and I SHOULD technically get a raw mark of 90 in the final...I should get a band 6. Who knows though I guess...I know a lot of people do well in Bio, so it's tricky to get those top TOP marks. However TECHNICALLY, if you came first in your school, you can get 100 in the subject. *Shrug*
