I couldn't find the Confuser either, so got a copy of an equivalent (Question and Answer Simplifier) published by AFE. The sample questions we almost idnetical to those in the actual exam.
Didn't use it for my Air Law, but should have as I only scraped it whereas all the others I've got 95% (so far!). Mind you Air Law is such a dull topic with lots of useless crap to remember.
