Hi, I have the 2012 edition of Cambridge Checkpoints Business Studies. The content follows with the 4 main topics; that is - Operations, Marketing, Finance and HR. Each topic covers about 7 pages of length, thus it's useful in exam periods. Then follows HSC past paper from 2007 til 2011, with suggested answers included. Lastly, it comes with study-cards, although it does lack some other dot-points in the course. Overall, my personal rating of this book would be 7/10.
I haven't checked up Excel yet, but I have StudyOn Business Studies, which is an booklet and online study-cards where you can answer questions online and on the booklet. I personally find this better than Checkpoints - personal rating of 8.5/10, but that's just from my perspective.
Good luck with the other comments mate.
Cheers
