I know like 1000000000000 people there, and 20000000 who applied there externally, it's only about 500 metres down my road :P (CRGS)
When I was in year 11 this is what happened:
People in my years mock results, who got in:
a) All A*s-As (she got 11A*s in the end)
b) A*s, As, Bs and a C (Got 10A*s and highest in the country for AS engineering in the end)
c) All A*s-As (got 9A*s 2As in the end)
d) my ex-best friend; 2A*s, 5(?)As, 2(?)Bs, 2Ds (8A*s 3As in the end)
alot of other people i know got in
two girls got offers then pulled out, one had 4A*s then As and Bs, the other had 10A*s
The people who got rejected (like me
my interview was AWFUL), some got amazing grades, some got averagey grades, just didn't stand out i guess!
hope that helps a bit
