What you do is stop worrying about it. Focus on ensuring all your personal affairs are in order so you can focus on training.
Trust. The. Process!
Skywest has trained literally thousands of pilots this way. If they believed you needed any of the info ahead of time to be successful, they would have provided it.
When you show up, just be ready to learn. When studying after class, remember that the most important thing is the thing you are working on the next day.
You will have 24 hour access to the training center if you want to practice on the Fms Sims or use the touch screen computer based procedures trainer.

They stopped sending the memory items and limitations in advance? When I went through training (2014), day 1, hour 1 of indoc was a memory items and limitations exam. We had all had a few weeks to memorize that stuff. I guess things have changed. I can still tell you the max takeoff weights of the 3 variants (53,000 , 75,000, and 84,500), the max speeds (.85 / .84 / .82) and so on and so forth. I'm surprised they're not sending that to everyone in advance.

But if that's the case now, as other posters have said : trust the process. Skywest has trained countless thousands of pilots to fly their first jet. Show up ready to learn and ready to spend most of your waking hours working hard, and you'll do just fine. It'll seem overwhelming at first -- that's normal. It really does all start to make sense as you get further through training.

Having been through OO, SWA, and UA training, I can honestly say that OO training is on par with SWA and UA training quality. The only people who run into trouble are those who just refuse to put in the effort. Everyone who shows up ready to work hard, does absolutely fine. Relax and enjoy the ride!!

This is news! The 24 hour access does make me feel a bit better at least for this section.

I have as many affairs as I can control in order. I’ll try to start relaxing, it’s just that I’m such an action-oriented person. If I’m not ahead, I feel behind.

This was also my assumption about the test first day (granted it also came from someone who went through training around the same time you did) so I can only hope they pushed the first test to at least a few days after class starts or else someone really doesn’t like me. 🤔 (maybe the recruiter I bugged incessantly for the past year)

I’d nearly give my left arm for anybody’s notes or study guide at this point. I really appreciate those numbers you threw out and I’ll put those in my (currently measly) notes that only had aircraft dimensions until now!

I went from E-175 to Guppy. I didn't think it was too big of a deal. In fact, I think the CRJ's lack of autothrottles and VNAV is a bigger obstacle to overcome than what era the overhead panel is stuck in.

There will be a welcome letter document given to you at some point that will outline a general training schedule, but I'll set your fears at rest. Indoc is 6 days long, with day 6 being the first test (this is NOT aircraft specific). Then ~15 days of aircraft specific training with a few tests towards the end of those days.

I commend your enthusiasm, but you are placing way too much pressure on yourself.
The worst thing you can do to yourself is learn the wrong thing now. It will make it that much harder to learn it the right way.

You are trained for a SINGLE variant (200) during initial and are NOT expected to know anything about the 550/700/900. As far as you are concerned, they do NOT exist.

For my training in spring last year, the limitations and memory item test was part of the Ground Validation, which was day.....9 ish? of Ground, which was after the week of indoc and the do-Systems-CBTs-in-your-hotel-room week.

This is why it's a terrible idea to try to get a jump on studying ahead before you are given the official materials. If you wrote down those #'s in your notes and memorized them - you just memorized wrong information. Speed limitations for the 200/(550/700)/900 are .85/.85/.84, and in RVSM it's .85/.83/.82

Just chill and be ready to study when you get there. You'll have 50 something CBT's to do ahead of time that won't make any sense to you at all until you actually start putting the procedures together in class. As others have said - the most important thing is just the next thing. Spend your current energy on solidifying the things that will make it easier for you to be gone for 2 to 3 months. You'll be absolutely sick of studying when you get done. No point in adding to the misery now.

This is better advice than I just gave. I actually found my old CRJ limitations doc buried in my Google Drive and you are indeed correct.

It's a bit simpler at UAL. We fly 5 variants of the Guppy and nobody expects us to memorize 5 different sets of MTOW, MLW, MZFW, fuel capacities, etc etc. We just refer to the laminated card that's on our lanyards. Saves brain space for more important things.

(Plus, show me a Deuce that will actually do .85 and I'll show you an airplane that's shedding parts...)

I had to ask for relief from a speed assignment the other day because they wanted .77 and I was struggling to get to .74.
