The CTC course is not an integrated course, it is a structured modular course, the same as the Multiflight course advertised on Pprune. I would love to see the answer to the question you asked on the
Oxford forum .
The Australian course asks for a lot of money upfront, something which Clive Hughes would say is a big no no. However at the bottom they do stress how the course fees are protected by various schemes. It would be worth researching these first though before sending £23,000 overseas!
