Before going in, make sure you're instrument skills are SHARP! Read up a little on FMS systems. Believe it or not, my experience with FMS on Microsoft Flight Sim helped tremendously. CRM is going to be your friend in the sim. It'll be addressed in a little bit in the "indoc" class. CAE has it's own SOPs which you'll get in initial, which you should learn by heart. Other than that, don't worry too much about getting a head start. I came into the program with no jet experience and 600hrs, so if you're a sharp pilot, you'll be just fine.
