i have both of the excel ones - the study guide as well as the practice papers one. i havent really used either, except i used the practice paper one before my exams to just do some practice q's. if u just want practice papers and questions then the practice exams one is good, if u want it to learn how to do things and explanations, then i'd recommend the other excel one.
the book that the mathematics association of nsw is also good for practice papers, it has a few past hsc ones plus other practice papers.
