I agree with Ann - is there anyone else in your Uni who can advise? Student Union? Or, your uni should have a complaints procedure, which may suggest where you can go to discuss things (I'm not saying make a complaint, but this might point you in the direction of someone who can advise). If intercalating is not an option, would going part time work? There may be benefits you could get if you intercalate - I'm not sure about this, but if no-one in your Uni can help, your local citizens advice bureau may be worth a go.
