aptitude books
Hi pilotvd, the verbal reasoning is not a grammar test. Its a reasoning test! Hence the excercises that you were talking about. Search for verbal reasoning on pprune, I found a few and they were very good. I think the important thing is to get your mind working, of course doing the same kind of questions does help. In general, look for books on Aptitude Testing rather than IQ testing.
