Bath Spa University Interviews!?

I haven't seen many, if any, threads on interviews for bath spa uni! I recently got a conditional offer for Environmental Science at grades CCC (which was below my predicted) but with the invitation to attend an interview to potentially change my offer to unconditional if firmed! I'm really excited about this BUT, I don't have a clue on how to prepare, what may be asked, or overall what will be expected of me to know? Is there any preparatory reading I should do, or any specific areas of knowledge to brush up on? I do love the subject, hence why I am studying it next year, so I'm confident I will do my best regardless... just still nervous!

Any help, even outside of this subject area, would be appreciated!
