hahaha, that's probably the most likely outcome(MUEP Chemistry) however I might just apply for something like math at UMEP as a backup.
With the textbooks you will need to get a new textbook as there is new stuff being added into Methods and Specialist Mathematics (I think something like 1-2 chapters).
The Methods textbook from Cambridge has been released but Spesh still hasn't been released. 
Sorry to butt into your thread, but it's been released and has all been printed!
Dr Evans happened to be my Uni Maths teacher this year, (for all you lucky ducklings who are doing Monash Maths at Scotch next year, you'll get to meet him)

and yes he's confirmed that they've all been printed. As for availabilities most of you will have to 'unfortunately?' wait til booklists have come out. For some schools that may be earlier, some later
Just take a nice break and relax.
Don't get second hand textbooks because the study design has changed and they've refined the old exercises and stuff like that too. Although it probably will be possible to share a textbook with a friend at school if you don't feel like you'll use it (I barely used my Methods/Specialist textbooks this year).
