I sat Air Law a couple of weeks ago, and used the Confuser right near the end (somehow got 92% by the way).
In answer to your question, for my Air Law paper, the question format, the question itself, and in some cases the order of answers were the same as the Confuser.
There may be a couple of words here and there a little bit different, but it's pretty much the same.
In other words you'll be in the exam and think - I've had this exact same question before.
Like the others say, learn the subject first.
A thing I found useful with the Confuser was to answer 40 questions, mark them, look up the examples, then re-do the questions again. The second time you do it you'll be much quicker. Mark it again, and look up the explanations again for the ones you got wrong.
Then do questions 41-80 (say). Mark as before, then "just for fun" go back and try questions 1-40 again. Before long you'll be getting near 100%. Continue until you do all 120 questions in the confuser.
Make notes of things that keep on confusing you.
Make diagrams of things like separation minima, airspace rules, quadrant rule etc. (If need be, as soon as you are told start your exam scribble any aid-memoirs down on the scribbling paper they supply you.)
Try and reword things in your own way. Also get somebody to test you.
I also agree with nadders - go on
www.airquiz.com, the exam papers they set are different each time.
