What Zap said. You will have to do all the modules in class to get credit. Learn the flows, limitations, lights and switches. I just passed my oral yesterday.
Your EFB will have the FRM (Flight Reference Manual). It's fairly light systems reading compared to what most type rating programs (i.e. Higher Power) would expect you to know, but it covers all the bases.
While I'm all about the K.I.S.S. principle, there've been a couple of times I wished there was a bit more detail in the company-provided literature.
