Nope, Two procedures lessons in the FTD; in the sim you have a maneuvers training lesson and an MV.

For groundschool, you can download the differences slides on the flight ops website. I'd also suggest the differences supplement. Now the 900 has its own systems manual which helps. Only thing I'd really study ahead is limitations.

Test is 50 questions closed book.

Differences is incredibly quick. For OE the biggest single point of focus is landings. Coming off the 200 you're gonna try to carrier land it. Six legs is the min but they usually try to build a trip with 8-9.
