The MCC is one of those courses you should enjoy. Personally, I wouldnt worry too much about studying for anything.
I am sure you are aware, that the course is designed for you to enter the world of the multi crew environment and you will be primed with all the skills necessary to complete the course, with no real pre study required.
If you do it in a full motion SIM, its a lot of fun.
Enjoy it and all the best.
