please dont despair!!!! i too had an instructor i neither got on with of found helpful... by the time i raised the issue i was too long into my course and was advised to stay put.
in hindsight i should have changed straight away but i was a humble student who knew no better. you are paying for this remember, ask in a polite but firm manner for a time served older insructor who really wants to be there. please do and let us know how you get on you will be amazed how well you progress.
