Jay,
From what I've been told we have to study the bulletins, 19A rules & regulations, pay practice, running time, speed calculation and some general contract knowledge. If you look in the "new york city bus" section and look in the "what is the standard B/O day like" thread I broke down how to pay a run. You can print all the bulletins from the kiosk in the depot. PM me your e-mail I can forward you a copy of the contract, running time and speed calculation formulas.
