I've had 4 cfii students. This is one of the cheapest and funnest ratings to get...Other than actual flight conditions or actual flight time you can do almost everything at home. Know inside and out front to back...your approaches, low enroute chart symbols etc, pts, instruments, rules and regs etc. I had one guy that was up to par with flying and knowledge and just needed work on GPS approaches and we had about 6 0r 8 hours dual flying and maybe a couple hours of ground. I've also seen it the other way with a student coming in non current/proficient, not up to par on the oral exam stuff. We spent 30-40 hours just flying approaches

You'll almost positively get asked on how to give an IPC too. Get a II PTS. Good luck and have fun!! Just remember...Your not a II until you almost get puked on by your first couple of students that are under the hood!
