I'm sure it varies from state to state. I have a PA class B with airbrakes (straight truck only). I studied the PA commercial driver's manual pretty well and had no problem with the written test. You should be familiar with the mechanics of airbrake systems, there will be quite a few questions on it. Pretrip was pretty simple, and the instructor did guide me a little bit. Just read and memorize the book stuff for the written. As for the driving, it's all in the skill. Can't help ya there!
