I agree that it would be hard to improve a kid's score. Yes I heard the questions but I only heard my DS's answer to them and they weren't things like what is 5+5 where there is clearly a correct answer that could be taught and memorized. In most cases I don't know what would have scored points and impressed the tester and what would have been average or below average. Many of the tests also had something visual involved which I didn't see and even if I did would have a hard time reproducing.

The tests are also done in such a way that the tester keeps asking progressively harder things until they get a few wrong. Having sat in on testing for my 6 year old wouldn't likely help me coach him when he retakes it in a few years.
