If you are thinking of doing your MCC Course I would highly recommend CRM Europe in Maidenhead UK.
I finished the Course there a few weeks ago and I have to say that I was pleasantly surprised by the quality of the training provided. The course was very well set out and the instructors were all ex-Training Captains for large British Carriers with huge amounts of experience.
Both the Theory and the Sim sessions were very interactive and unlike what I have heard about other places you are not just a number there and the course is delivered only during the day (heard some SIM sessions are booked even at 2am elsewhere!)
I have no affiliation with the school whatsoever but I am genuinely grateful for the training I was provided there, hence this recommendation
It was definitely the best part of my Flight Training!
