I'm too embarrassed to mention the number of times I attempted the CPL Air Law exam. The worst thing about my result was the fact that I missed out by one mark on two occasions, my situation with Dad's passing did not help me prepare for the exam thoroughly but I was determined and managed to get 93%.
I hope I never have to sit another exam the same number of times.
Make sure your CAO's, CAR's and AIP's are tabbed and up to date so that you can find the info quickly. The exam takes about an hour to do, the rest of your time should be spent checking your answers..
