I think their talking about the real exam mark mate, not the total scaled mark!
Your raw exam mark is what you actually get, but they change that mark to make the course look more respectable...
Like lets say the average is a fail, 40, the change that to some respectable, like a 60, people in the top part already get further pushed up accordingly
Im glad i did General as oppose to Advanced, Advanced is a shit course, memorising formulas and shit, and doing stuff that i never use again in my life - fuk that. General maths is alot more practical, shitthat if you really wanted to applies to real life situations! Although General scales down, i would do alot better in general even after scaling - which is better, top of general or bottom of advanced!
