I have had the same problem with AGK,
Failed by 1, then by 2, then work as hard as ever and failed by 4!
Not looking good with the 3 year period closing in fast!
I sat and failed AGK(3rd time) and was not allowed to sit any exam for 2 months(fair enough), 2 months later I sat air law and missed out by 2, so now I cant sit ANY exam for another 2 months! with only AGK and air law to go, so its going to be 4 months since I sat AGK
Before computer exams you could sit any or all exams over a 3 day period regardless of passing or failing subjects every 3 months this could happen , why did this have to change?.
One day someone's going to lose it and go up to Canberra, just hope its not me!
