Sourapple, if there's anything you can send them (within reason) that they haven't asked for, but that might help your application, then send it. Things I'm mean are copies of degree certificate, or even better an offical statement of your module results from your uni, if you think this would help. Maybe a CV or covering letter, as suggested previously, if you think these might work. Remember, you're trying to sell yourself to them, and as long as you are truthful, I don't think you have anything to lose
