My advice, having sat all the exams in the last few months is learn the contents of the books the best you can, as you will always need it and if you go onto do your ATPL it will give you a good understanding. But do as many of the confuser questions as you can. You will find that doing the confuser on it's own will pass you but you wont actually learn that much.
In essence though the confuser is about 90% right!
