Seriously, relax. This is my 3rd carrier and my 9th type school. They do things a little weird here but never have I seen any group of instructors and check airmen who are so committed to getting you through as I did here. They want you to succeed and this is a very low stress training event.
If you put forth any reasonable amount of effort, you'll be fine. Enjoy the cheap drinks and fried chicken at the Anatole. Use their instructional lingo, and talk to the class ahead of you at the hotel. SWA is definitely not a training mentality of trying to get rid of people. No tricks, no surprises. They just need to do a little better on days off during the event, you end up using those days off for OBS flights and that's a drag.
Welcome aboard, great people here.
