If one needs drilling, then Low Chin Ann's style of teaching would be suitable as described by Topace. Attempting the questions provide a good gauge of how well you know about the paper.
I say this because 4 of my friends who attended Philip Woo's class for the last session didn't make it for F8. He conducts test every now and then, but during classes there is no trying out the questions. His explanations though, are clear and concise.
This isn't a paper like F4, where throwing everything you got after storing it in your mind will work. The audit paper has different questions every single time, which leads to different style of answering. Throwing back everything will put you out of context which leads to a lower chance of passing.

Nice pass rates there for most of the papers in my opinion.
