My position was the same as Student's last year, creamed the verbal, and messed up the maths...
To qualify the test... I believe that verbal reasoning is important for flying. Essentially it is a test of your ability to think logically and quickly, whilst only considering the facts given. If that's not important then I don't know what is.
I used a variety of 'Kogan Page' books. They're the glossy paper backs found in the reference or careers section of good book shops, they all have a picture of a graduate in mortar board and a gown on the front. I found them quite good practice for verbal and maths.
