Thanks Tinstaafl and AirUK !
I think I have a pretty good idea on how to tackle the studies from my side and what to expect. But I'm still confused whether those revision sessions and support from the school are that important. There are good reviews for all 3 schools' ATPL courses and people have succeeded with just one refresher session Bartolini offers and splitting the exams (like I'm planning).
It's rather the question of experience, if you would've done the ATPL's again, would you still go with one refresher session or definitely several ones before each exam sitting.
And then PadPilot vs Bristol (at least Bartolini used to use Bristol, but switched to PadPilot. Their official reasoning is PadPilot is better for the students, but reality could be they got a better deal. Nothing wrong with that, just doesn't help me to decide
)
