RyanRs,
You could have reschedule the exam, did you know that I also took Air Law recently but before I took the exam I rescheduled it twice because I was not prepared, there was always a combination of professional and personal factors affecting my study so I decided to change it for another date, and the school were more than happy to help the student. Afterall you are spending big money with them.
I passed my Air Law with a combination of studying the book Air Pilots Manual (Use to be the old Trevor Thom books), PPL Perfector and AirQuiz. I also used a good friend of mine retired pilot who flies for leisure now to fire some questions my way. I also like the CBT's available I have a couple and I think they aid the study.
