Yea, that's where the training is, in a giant flight sim. Other than the standard steep turns and single engine flying that you have to demonstrate there's not a whole lot of actual flying skills needed during the training. 90% of the time you're just playing a video game on the cockpit displays, flying the panel so to speak. It's all IFR flying, I would practice all kinds of approaches and definitely look into YouTube videos on how to fly using the FMS.
