Ahhrgh. 1 mark lost on VCAA Exam 1 2006. I am seriously going to stab myself 
haha same.
I lost 2 on exam 2...On the most retarded things, oh well, I'm gonna do 2009 later today and I better get full marks lol.
I lost marks on even more retarded things. I'm just finishing the marking now. If the question asked for intercepts, does that mean the answers need to be given as coordinates. I always thought for intercepts, you just give the relevant x or y value... ?
Anyway, my dumb mistakes. Q4. Choosing the matrix in the wrong order. That is a bloody further question and I still stuffed it.

Q11, didn't even think to solve it in the CAS. Dumb 10 second question took me like 3 mins and I still stuffed it.
And in Extended response, Q1 part b.i., stupidly made the mistake mentioned in the examiners report of solving cos(x)=1/2 and forgetting the domain was [0.2pi], so gave positive and negative pi/3. If we're not doing consequentials, then that cost me 3 marks in total.
These mistakes are really pissing me off. Knew how to do the whole paper, yet still lost 5 marks. How do you improve damn it....!
