Hmmm, with all due respect to everyone who has posted here, i find that the leading edge text book is the best. It not only gives you HEAPS of relevant up to date examples (which you need to get a band 6), the notes are very easy to understand. Most important though, it has nearly no irrelevant information. The maker used the syllabus to make the book, so all the syllabus is covered thoroughly. heeheh, why dont you try it? You have nothing to lose, right?
