OK, Here we go
You have 7x written exams to do Airlaw, Met, Human factors, Aircraft performance, Aircraft general, RT and Nav
Then you have to do and 8th exam, this is however an oral exam, you are given a route, and basicly you have to talk your way through it. The examiner is the ATC, you are the pilot.
I suggest you do this exam right at the end, this way you will have loads more experience with RT
