10 hrs training should get you through. Its a little harder than the JAA ME rating, you have to give a Vmc demo plus engine shut-down on the flight test....and not forgetting the oral exam.
The flight test is pretty much like the PPL flight test without the Nav. Steep turns, stalls, circuits, etc, plus all the asymetric stuff, 'random' engine failures etc...[on mine the examiner 'failed' one engine on the take off roll by pulling the mixture]...
