First off I did not take the test, officially, but I have done it a few times. at first , with out a clutch it was strange but you soon learn to compensate, you can't give control over to the engine.
By that I mean you set an RPM a little faster then you could make the cones and hold it, from then on you control the speed with the brake, just like you would slipping the clutch--
sure it takes a little practice but is is well worth the time to learn.
The same thing works when your trying to go real slow. 8)
