I
The fact you have already alluded that you needed three instructors to just pass you driving test leads me to think you maybe need to look into yourself because once you do get on the road you are all by yourself no one will be there to hold your hand. You are accountable for everything.
Did OP want three instructors? I got three different instuctors forced on me when doing my Class 1, I didn’t want that, and it certainly did not do me any favours, as each one had their own way way that things “must” be done and there was little correlation between them.
