Feedback, feedback, feedback.
I'm not a fan of studying for exams by learning feedback questions. In general, I think it's a very bad technique. But I'll make an exception for Air Law. The questions are so obscure, with many of the feedback questions I saw being very similar but subtly different, such that there really isn't any other way of learning for it.
Hopefully, you've picked a school which is good enough to give you enough feedback questions to get your through the exams. My technique was to study entirely from the feedback which my school (Bristol) gave me. They also gave references to the pages in their manual where the answers could be found. Any questions which I got wrong, or wasn't sure on, I looked up the answer, but also looked up the relevant section in the manual and read it thoroughly. Got tripped up a few times by finding a question on ICAO, learning the answer to it, then finding exactly the same question but this time based on JAR, which has a different answer. Thankfully, the feedback was good enough that I managed to pass - whew!
Good luck!
