Met a current student last week. He carried 3 stripes, so he obviously had passed stage 3 (I believe they call it PT3 there). He was about to start on the twin, followed by IR routes and then the 170A. This guy had paid an extra £6K to complete the course and said this still worked out cheaper than Oxford.
He also mentioned that the MCC course is now done on a B737 sim near Gatwick (?) and I wonder whether FL500 have an input in this.
