Osborne Books self study

*Silly question time*

Apologies if this sounds really stupid everyone. Basically I have just purchased the Level 2 and Level 3 AAT books from Osborne Books. My question is, should I get to a point where I feel quite confident that I can answer most to all of the questions in the workbook, would this be enough for me to be able to pass my exams. And more to the point, could learning from the books allow me to achieve grades as high as Distinctions (AQ2016). Or would I need to access more difficult material in order to achieve this?

Thanks in advance.
