Here comes the problem Phil, I think I finished my exams under amendment 3 but they don't think like me.
One of the big changes, at least here in Spain, with the amendment 6 was the general navigation exam. Under amendment 3 the general navigation and radio navigation exams are together (two parts in the same exam and the result is an average between both) and under amendmet 6 the general navigation and radio navigation are separate exams for a CPL(H). I only did one exam like in the amendment 3' exams.
I have a certificate from my CAA with the results of my exams and the exams that I passed to get my CPL(H) if you are interested.
Regards.
