I came 1st in my class overall and got a mark of 85, but my teacher scaled it and she told us. She said she would scale it to what she thought we would get in our exam. And she was very conifdant i would get a band 6. So with that data what raw mark do you reckon i would need for an overall scaled band 6 at the end of the processes of scalling and HSCing(whatever)???
