I dunno how many times one has to say this before people finally take notice but there's only one school that will get you through the ATPL's quicker and better than anywhere else and that is BRISTOL GROUNDSCHOOL.
Quite frankly nobody else comes near them. I've seen pretty much the lot too so if you don't wanna listen then lots of luck you'll need. . . . .
If it's overwhelming details and non related info you want then you'll have your work cut out passing. Fishing for more than the basic minimum info you need to pass the exams is a risky buisiness when it comes to ATPL's.
Also, I would avoid over complicating matters by getting your hands on all the notes you can. Stick with one school (ideally BGS) and leave it at that.
VFE.
