You will not be spoon fed, need to know how to study on your own (IMO why people with college had far greater success rates), and submit to the fact that theres not much 'self paced' about the 'fast track' program. It either works for you or it doesn't. Most CFI's know the areas students struggle with and will do extra ground to fill in the gaps. However, if you expect a CFI to go over rote information repeatedly or when it comes to check-ride prep time it's obvious you haven't been putting in the effort you might want to study up on the refund policy.
I guess the answer is a majority of it falls on your shoulders by completing the readings, videos, and assignments. You'll get one on one ground, I'd say about half of that one on one ground time isn't actually receiving instruction more than it is verifying you're progressing normally via mock orals and the various evaluations. From what I saw, this was the area where people failed to fully realize how it all worked, how much effort was involved, or simply couldn't absorb the information fast enough. This often culminated in a $45,000 private multi, or in a few cases a $20,000 joyride never completing one check-ride at all.
Not saying this is the right way do do things, it's just the ATP way. Just have to ask yourself deep down if this will work for you, because it can get pretty expensive if you're wrong.
