All right, thanks! I'm planning to go to a music shop sale tomorrow, in which they're having a month-long store-wide sale, with 40% discount on all books.

I shall get those recommended, and some other piano books.
Another question: How different is a TG theory exam? I was looking through a pamphlet of TG exam fees, and realised they had theory exams!

I'm not too sure on the structure of the exam though, like the type of questions, format, how different they are in comparison to AB's...
Could anyone shed some light on a TG theory exam? Doesn't have to be grade 6 theory, but that'll help, nontheless.
