Taigun, there's no such thing as overtime. You do get flight pay per hour though. Day off payments are 1.5 x standard daily rate plus flight pay. The roster is usually 5/2, 5/2, 5/2, 5/3 (ish)! Like MC says, forget the OPS manualy really and concentrate on the Memory items and cockpit flows, that'll do you to start with.
I'm on my OPC early January so likely see you there
Good luck.
