I know the conversation has died down a bit, but I would fill a bit amiss if I didnt say anything. But rivalry you are setting yourself up for a big fall. Your focusing to much on the little things and you are missing the big picture. I cant understand why you are so stressed about the HSC - yes it is important but realistically, the amount of pressure it seems to be putting on you is disproportional to its overall significance.
To be honest, with your attitude you wont last in law. You have a great work ethic, but to get through a degree like law you need motivation to compliment that work ethic. Law is a very very very difficult degree to do if you dont truly have a liking for it - if you end up hating it, your motivation will run dry and inevitably your work ethic will suffer. To make matters worse, all this pressure you have put on yourself for the HSC will compound and eventually, you will run out of gas.
Last year, a 99.95er (not going to say who but you can probably guess) asked me for advice about doing law and I pretty much told him the same thing as I am telling you. They didnt seem to have a strong interest in law but they ended up doing it anyway - last I heard they were thinking of changing (I never confirmed this so if I am wrong, apologies). This isnt an isolated case and it is extremely common with law - the cold hard truth is that law is challenging degree and if you dont have the desire to do it, then no matter who you are chances are you wont last.
Dont take this post the wrong way though - I am not having a go at you or anything. I just think that your mindset has been distorted by external infuences and this is going to affect you later down the track.
