Excellent place. As far as the question bank goes its the closest your going to get giving the CAA a taste of thier own medicine. ie making up for the extortionate charges, and them producing complete crap and nonsesne questions that dont actaully make sense! It reveals evry trick in the book they have!
At some points I was chuckling to myself in the exams. ( Having seen most of the questions before!)
There is no excuse really not to pass them all first pop.
