Thanks.
Advice about the MEI, know the systems of the airplane well, and be able to teach multi engine aerodynamics. Know the when you can fail an engine with the mixtures and when you have to only use the throttles, and what speed you can fail the engine on takeoff roll. Just talk to the examiner like you would a new student and you should be fine. My oral was about an hour, and the flight was 1.1.
The II checkride was pretty easy, if you use the same examiner, try to impress them with the first checkride and the second one will be a bit easier. The oral consisted of the flight instruments and regs. The flight was three approaches, 2 ILS and one PP VOR. I flew the first ILS to a missed, then the examiner flew the 2nd ILS and had me fail an engine on him and talk him through the approach. The VOR approach consisted of one turn in the hold followed by the approach all partial panel. He made me fly it to the final approach fix then he took the plane and on the way back to the airport he put me in an unusual attitude and then he landed the plane.
All in all, I had a great experience. It took 5 days and I got 2 ratings. If anyone is interested, it was at ATP's in Las Vegas.
