I agree with Genghis, and most of the others. Either find another school, or play along with them for the checkout, and then go back to your original way of landing.
Don't forget, though, that to achieve the POH landing performance, you will need the correct speed/height at the threshold,
and the throttle at idle from there on.
If you keep any power on to the 'roundout'/'flare' you will extend the landing distance considerably.
