if what AAg says is true then here is some info for you.
I planned to leave AAG after i had completed my ground school exams. I went to a few of the flying school across the middle east and they all asked me to redo the ground school exams. To make matters worse I had to resit the whole of the ground school hours!?
Why? Because I was doing the MPL.
If it is so easy to convert then why is it that i had such difficulty. I provided them with proof that I passed all my exams. Yet, they showed no interest.
If an MPL can be converted when u do the 1500 hours then sure;y u can convert the exams. Same books and same exams after all.
