Good timing for you!
I suggest first buying all books AIP, ERSA, DAPS, ERC L&H, etc, pretty much everything on CASA permitted list either in May or November because that's when the changes are published every year. That gives you 6 months to prepare with current books and charts.
I used Bob Tait book and worked >every< example from cover to cover. I also ended up buying Bob Tait videos and they helped with actual understanding of relevant rules and laws.
I also used PPE (pilot practice exams) and found them helpful too.
Finally, the pages in the AIP will be so thin from turning the pages that you will be able to see through
That will be your main book and all those can be downloaded in pdf format for free, however at the exam you can bring a paper books only.
~3 months of self discipline, between 1 and 2 hours every day, balancing between work and family made me a pass at around ~100hrs ppl.. I find any cpl exam now a piece of cake
Good luck!
