Do yourself a favor and skip the CRJ type rating. Save yourself A LOT of money. Your better off studying the Jepps and AIM in and out.
He's right. I've personally interviewed pilots who had their CRJ type ratings without a single hour in the actual airplane and they're clueless on the systems. Most say something to the effect "well, I got it over a year ago and don't remember much anymore..."
Know the systems of the airplane you're currently flying. If a procedure has you flip a switch, feather a prop, do something a certain way, know why you're doing it- not just because the checklist says so. Know Jepps, FARs, and IFR procedures.
