Neh, double post because I feel like it.
The other thing to note which might have a deciding factor is that on the letter I received, it mentioned something about teachers nominating students for the award. Totally forgot about this in my last post but this is what I reckon was what decided who got it. The girl who I said got 99.80 was a bit of a slacker in year 12 so I suspect she never got nominated by teachers. The 99.95 friend I mentioned was from a non-selective state school, so I don't think they even bothered submitting nominations in as no one in that school got them as far as I know. Lucky for you ILMM, McRob has received plenty last year, and with your academic record, I'm pretty sure your teachers were well aware of you and I'm sure they would've nominated you.
