Kash360,
You say you've spoken to the people at OAT and they said doing their ground school is not too important. You then conclude that maybe they are "Just trying to reel me in i suppose."
I fail to understand how you conclude they are trying to reel you in by offering something in contravention of their own policy. You must have spoken to an ill informed receptionist or something because that is pure tosh. They are very clear that they do not waive this policy for anyone.
I'm not trying to convince you to go there, but if your heart remains set on Waypoint, I suggest that you speak to one of their advisors who actually has the authority to enrol you because I am quite certain they will say you must do the ATPL theory with them.
