No, you don't have to read a lot in preparation for it ... or at least not any more than you're already doing for interviews (and I remember refering to something that happened in work experience). There's no set thing you're expected to say in answer to any question, just a general awareness of medically related issues and/or a logically thought out arguement, whatever conclusion you reach. The questions are quite structured. I would read the official BMAT book - that has a very good chapter on section three.

You can walk in with good logical thinking and walk out with 9, I'd imagine working on timing, reading wider might give you enough material for 12...although much depends on the questions you get on the day.
