Yeah they are definitely worth it for biology (that's the only one i've got).
Thanks so much for the feedback! ^_^
I'm obviously biased, but the big advantage I see with ExamPro is that the authors have
just been in your shoes! They know the stresses of VCE, they know the frustration of silly mistakes, they know the feeling of working your ass off for a 4 digit number. They're not a bunch of old guys/gals who sit in a room over a cup of tea and hardcopies of The Age who discuss the health risks associated with leaning on the back two legs of your chair. They've just been there and done that, I think being able to relate to the the authors more is a huge plus, wish I had the opportunity to have access to resources like this.
Oh and, as aforementioned, the solutions are pretty intense. Especially for Maths and Chem, they're pretty much supplemental textbooks.
