i think jacaranda is the best primary text book out there....
you need summaries and the excel book [and even possibly other texts] to make sure that you are on the right track with dot points.
it would need someone to manage it(ie mod) and that can be quite difficult, esp at this time, unless it is someone who has completed his/her hsc....but anyway it would have to be at the start of next year, its a bit late for that now i think....
