they don't usually let u take the exam home after u completed it.
If they were to let u take it home then if someone didn't do the exam then u could give it to them. So they must wait till everyones finished the exam b4 handing it out.
Not sure if u guyz will get the marking criteria, but i convinced my teacher to hand it too meeh to so i can learn eheheh.
BTW wat do u mean h0w to do the killer questions? Do u want to know how to do the killer questions on the CSSA trial paper? or u talking about the independant paper??
