WBA = Wolverhampton Business Aerodrome or Halfpenny Green as it's better known.
Good luck with your choice
I think at OAT you will be back of the queue for slots against the Intergrated students but have heard the MCC/JOC courses are good.
Officially it doesn't mater where you do it as it's just a tick in the box and most companies will give you another MCC course when you start with them anyway, so in effect a waste of money but a requirement nonetheless,
Still I couldn't fault European at Bournmeouth
