I really don't understand the school scaling marks thing. I don't see a need for it. A raw school assesment mark will probably be close to the raw HSC mark.
Oh, and it doens't seem fair. Say if two schools both do the same trial paper, and a person from each school gets the same mark. If one school scales the mark up, it appears that person did better. What if both people applied for scholarships?
Or if both schools scale the marks, but scale them differently?
