Compass does a great job with their AQP. It does require a lot more effort though if you aren't prior 121. Your best bet is to try to pair up with a prior 121 guy who can help you with the basics. Having said that, their pass rate is like 98-99% for new hires with or without 121. Just come to ground school with memory items and limitations memorized. Spend a good amount of time with the Systems portion of CBTs and you'll be way ahead of the game. Might not hurt to look at flows and profiles as well just to get a feel for them.
