look idk when you did your HSC but i can tell you, markers generally don't care anymore, the standards have dropped considerably. I mean for gods sake if you're so stupid that you can't BS to make it look like you're answering the question than you probs don't deserve good marks anyway. I mean you would have to of had your head stuck in sand the entire year, if you didn't soak up enough general knowledge about the changes in society under the Nazi Regeime.
point is it's not difficult, anybody who knows the tricks of the trade can go in with only a rudimentary knowkedge and walk out with 80% plus, I've seen it happen all too often.
