Mmmm ...
Rabid ....
You MUST go and see the Chief Flying Instructor of you training organisation and have a heart to heart discussion about this ....
I agree with Epiphany on this you MUST have a change of Instructor ... at least for this training sequence ...
Autorotations are considered to be very important and unfortunately for a budding commercial pilot ... the 'basic auto' as trained by an inexperienced instructor will just not do .... (and I shall not to go off on a tangent about my views on what level of experience a pilot should have before being allowed to instruct in Helicopters) .....
Good luck ...
