Obv I've only been through one initial, but 99% of them seem to be. Open the limitations section, ask a bunch of limitations that are marked as need to be memorized. Get the IAC (inflight emer checklist) ask a bunch of procedures (most want the ones that are not asterisked as required to be memorized, so you have to have the whole thing down cold, its only one page front and back though). Ask some general system questions both using the in aircraft systems screen, or the overhead panel as a guide or questions that use the outside the aircraft preflight photo book as a guide. That's it ~ 45min-1hr (time my vary if you stick your foot in your mouth at some point).
