I'd also be interested to hear more about doing the ATPL course through Bartolini.
The price certainly is good, and they do use the Bristol Ground School materials which I've heard nothing but good things about. Poland is also much cheaper than the UK to sit the exams.
I do wonder though about the ground school/ revision element of the course. I think I'd prefer to do it the Bristol way splitting the course into three separate parts (or at least two) rather than Bartolini's study everything and then do revision for all fourteen subjects in two weeks. How does this work?
Also, when do people sit the exams? I presume they don't do all fourteen of them in one go.
