Funny, on my feedback from BA they said I had aced the verbal reasoning paper, and I've wanted to fly since I was 5! Pity about my maths though
Anyway back to the original question, the type of test that you sit for the verbal reasoning is no different to the Nuffield or Longmann type tests I sat at school during English Language lessons. I bought a book called The Guide to GMAT testing for about £12 and it was stuffed full of examples and practise questions that will get you in the right frame of mind.
