The only personal experience I have with them , its for the RT test and I must say I was not impressed.
The examiner denied to give me a level 6, due to the fact that English is not my mother language.
I have studied at a UK university and I have IELTS and an English Nationality and he said he was very satisfied with my accent and my pronunciation but these are the rules he said.
I have looked to find this regulation but have not managed up to now.
Cannot comment on their flight training but this is what I experienced, instructors that are not up to date with regulations.
