I just started the ATPL distance theory there. From the pictures I think they might have a full in-house portion but I'm not sure.
I have not gone to the school yet but what I was informed; You through the 14k QB on AE with a 75%+ average then you go to the school for 2 weeks or so for briefing sessions and a sim of the exams. Supposedly after that you get the write off from the school to go start your exams. Regarding the other Polish schools the distance ATPL seems to be the same other than using AE to Bristol QB.
Although the back-office there has not been very easy with contact, the HT is a very hard-working guy and gets things done when he's available
