N2P,
Don't worry, even the professionals get confused. The whole thing is now very regimented in terms of production - just churning out at cheapest price on an integrated course someone to sit up front.
Try and do something different, rather than signing up for an straightforward 100k integrated course, and you discover knowledge on how it is done - under today's rules, which aren't yesterday's and won't be tomorrow's! - was one of the first casualties of standardised production.
Tempted to say: you should be asking all of this to any flying school you are thinking of signing up with. If they can't answer, then don't trust them and go to someone else who can.
But..... does anyone really know their way around this mess?
