Superpilot,
Think it would be an advantage to be honest, you've already got a head start with the theory, which makes the whole process a bit less stressful! I know of at least one guy on the scheme who had done all this Atpl exams ( via University ) before starting in Nz. Lucky bugger only had to think about the flying when he was there, more time for spending on the beach too!
Shouldn't be a prob
