Part time instructor in the Phenom here.
Take your time during the computer based training, but do not try and learn everything. Ground school will review all of that and add some more, but is very realistically paced (the 100 especially is designed for lower time pilots and owner operators). Normal day is ground from 9-2/3 followed by a 2-3 hour avionics lab. You get an extra sim versus the other programs, primarily to deal with the Garmin, which is a major hangup for some guys, especially the ex-airline drivers.
It is the only Phenom program in the world aside from NJ, so the sim does stay very busy and works from early in the morning until late in the evening. They're also down quite a few instructors, so you may have more than the normal two during sims.
Review what you can about Jepps, but you don't need to get into the nitty gritty of them, just know how to brief them and find the important stuff. FAA: JFK is the primary airport, but you'll also see TEB, FRG, PHL, DCA, IAD, RNO, SFO and depending on your company potentially ASE, EGE, DFW, TUS, PDX, SNA, and SMO. If you're EASA; EHAM, EHRD, EGLL, EGKK, LSGG, LSZH, and potentially EGLC, LFPB, Chamberry, Sion, and numerous others.
The program is better off than a lot of others at CAE because it's part owned by Embraer, but that adds complexities when you need something. I'll respectfully disagree with the post above, it's been the best program I've done at both CAE and FSI.
If there's anything else I can help you with, feel free to PM me and I can give you a call plus see if I'm teaching you any (I hope not, for your sake).
