Well done, snigs.
Now go back and ask your instructor WHY he hadn't given you the tip about using the heading bug as an aide-memoir to the heading. Darned useful thing when being radar vectored somewhere...turn it before acknowledging ATC.
But, I say again...well done. Trick now is to remember not to use that IMC rating in cold British clouds unless your aircraft can handle them. Wing leveller or not - even the Arrow does not do well when covered in ice
