I noticed no "second class citizen treatment" from the school.
You wouldn't during groundschool but the flying side of the house
can be quite different. Being trained a relatively short module by instructors who don't necessarily appreciate the nature of the type of course you are undertaking, far from Kidlington and competing with core business customers for the same resources you
may be disappointed. An 80% first time pass rate is not high considering the comparatively few modular students enrolled on Waypoint. The FNPTII's in Kidlington are basically King Air cockpits configured to represent a Seneca but that shouldn't be an issue.
Have you considered Bristol Flying Centre or one of the other reputable non-integrated FTO's? Continuity of training with one provider will not be a factor between the theoretical and practical components.
I would say the most important decision you make with modular training is where and how you build the hours leading up to the CPL module - there's not much time in the course to put right bad habits. Best of luck with your decision because I'm afraid, as modular goes, a successful outcome depends a great deal on hard work and a lot of luck!
