Would say Air Law was one of the easier exams. 3/10
About 30-35Qs in the exam.
I had seen a variation beforehand of each question in the AFT practice exams so I knew where to find everything.
I used the CAO's CAR's and some AIP's in the exam. The only Q that I got from the DAPs was that Curfew one.
Didn't even open a map (which was good because all the ones I had where out of date).
If you do the AFT practice exams then you should have no trouble.
Good Luck, but you wont need it.
