I used COPTRZ to do my PFcO to GVC conversion course. It was a fairly lengthy process but I can honestly say COPTRZ we're there for me each step of the way. The course itself was done online and found the coursework informative and presented in a genuinely professional manner. The individuated exam at the end of the course was strict but didn't mind one bit as I feel this needs to be done correctly. When I did my PFcO 3 years ago it was given that you would pass the course, this new license did take some getting but that is what I was after. I now feel happy to run my drone business as I am fully up to speed with the latest criteria. Well Done COPTRZ
