Tancar, it is beyond me why you would want to pay 6550 Euro for the MCC course, it does not improve your chances of working for RYR, it could actually have the opposite effect, as they will be expecting much more of you at the sim check.
As an example you can go to Oxford OAA, and get 737-400 MCC for £2550, and their ops procedures are also very similar RYR, but at half the price.
For MCC course or a Sim check you are not expected to be proficient on the type.
