Good schools should not be starting from square one. PPL knowledge should be assumed. It is only because people turn up ill-prepared that good schools might have to start from the basics, they prefer not to as it then gives time for the more complicated material to be taught in more depth. There is a reason that a PPL is required to start ATPL training.
Good schools also bend over backwards to help out those that work hard but still struggle. Appearing in the classroom with a shiny PPL but without the knowledge that should entail and thus delaying progress in the class is not going to put you to the head of the 'works hard' category.
