My two cents
Just to throw my two cents in. I came over to study the rotary course, through CAA. I started in May and received my commercial license last week, so I took me just over five months to get qualified. I had basically one on one tuition through Gateway Helicopters, which was second to none, I was put up in very nice and comfortable accommodation, the company have treated me well. I know that you could do it privately and it may be cheaper, but it has been hassle free for me, and living with guys who are studying the same course and going through it, was very beneficial for me also.
Obviously some previous students seem to have a problem with CAA, i can't comment on that as I wasn't here then, but I have no complaints at all. I'm working with the guys at the minute to sort out work after Christmas and looking forward to it.
Well there you go.
