Someone can probably answer better than me, but

In terms of package, upto you how much you are willing/able to study per week from now untill test date. Explanations of everything is available but you have to get the actual PTs yourself. And in terms of technique, if you look at study schedule it will lay it out for you, you do lessons first, then start drilling PTs when your done. And I dont think any books are needed to supplement.
