XD Do something that's out of the ordinary, its advised to 2006 students not to texts suggested by teachers, or already in Study Guides, because countless people have already used it.
So, practically if you see your related text mentioned around alot in BOS, then you know its not going to help you score high in HSC. I went to almost 4 libraries to borrow a geographical magazine, which talked about the adventure of 7 aussie climbers to Antarctica, and the other one is Seven Years into Tibet...I hope it'll score good in my HSC.
