I agree. And isn't the idea of a test to find the people that are best a doing something. It doesn't really matter how much preparation goes into it. So maybe someone that works really hard to be better than others at something is more valuable than someone who is naturally bright? For example - a naturally bright lawyer isn't as good as a 'good' lawyer that tries really hard to be the best. Being good at a test shows that you'll be good at whatever the test is trying to find - no matter how this is achieved.
