Decent paper. 2012 Q16 was MUCH better.
However, in regards to some ideas raised,
Right now, as a HSC student, one may think that a good examination to differentiate ranks are of immense importance.
But once we all complete our HSC, get our ATARs and head off into University, when one reflects back on these things, they will seem trivial.
We have to consider about being in the shoes of teachers and examiners. They have long passed this stage and their life is not dedicated to produce a 'good' exam. Most will have families, friends and other dedications that they rather invest their time in. Working as a teacher is just a means of earning an income, which is the reason that most, if not all, people work.
So, taking all these into account, you can't blame examiners for an easy exam.
Furthermore, 2009, 2010 both had a question in their Q8s ripped from past HSC (circle geo involving locus, the induction question with validity of statement), yet people are still saying it was good. So, just because this year had taken a question from a past HSC, why are we all fussing over it?
