I thought it was relatively short compared to the 2012 exam, As I attempted the 2012 exam 3 times in practice and didn't finish it once in the allocated time, whereas this exam I finished with 10 minutes to go, could just be the pressure and nerves.
The questions weren't too hard as well, some of the question however weren't well specified by VCAA as there is a big difference between the impact of a policy in the short term and the long term, and some questions did not give enough marks for you to provide the whole answer.
Overall the multiple choice was probably the hardest, in terms of in class teaching, as there were a few questions that could only be answered if you were aware of the ideas presented, but I still think there will be a significant amount of 15/15's. As a number of the answers could be ruled out, the biggest challenge will have been identifying what the question was asking as some asked for 'not' or 'least likely'.
I believe it was still easier than the 2012 exam, but defiantly harder than the many others before that. And the A+ cut off may be around 77-78/90, depending on what the markers are looking for in the extended response.
