I'm very surprised a raw mark in Business studies for a B6 is less than Economics, I suppose the good aligning despite scaling is true.
Is it just me but how are you meant to know how you will go in raw marks? Because I assume the HSC markers mark more harshly than at school.
Oh well Yr 12, I'll just study hard, have the estimated raw marks up for Band 6/E4 in all my subjects because that's my aim. Band 6/E4 in every subject, though I would still be happy getting mainly Band sixes and one or two high Band5's/E3s.
