Strongly advise you to do it on a jet sim, but only if you can afford it. As well as gaining the MCC qualification, you can enter 20 hrs jet sim on your CV. This gives a good introduction to anticipation of speed and inertia regardless of how inexperienced you are. In the old days many recruiting companies liked to see what they called "Jet LOFT" sim time (a bit like an MCC course). Even if you felt your handling was dreadful it makes for less of a shock when you get your interview sim check.
And remember, you are not being examined on your personal handling skills on an MCC course.
Find the cheapest jet sim you can. I did mine on an ancient HS125 sim with no motion and no visuals. It DID make the difference when it came to getting my first job.
