I managed to get through my course using the official Boeing FCOM/QRH etc. and the unofficial 737 simulator survival manual which is a fun read, covers flows, profiles etc. as well as where people usually f... up during the checkride

Sit back relax enjoy the ride, what I mean is do not get all wound up about it, enjoy the course and study.. no need to freak out.. personally I didn't find it to hard.. just be well prepared, also for the sim sessions. I spent two hours before each sim session to study what would be covered during that session, read the reference documents for each item on the lesson plan and there wasn't to many nasty surprises
