I have not fine opinion on IQ tests. If you ask me, that's not something that's just used to mark peoples. It is something what you can learn. It's just question of the efforts you give for that. I like them but I don't consider them for nothing more than a game - my opinion.
My first result was 133 and today I can get over the maximum quota which can be measured here, 158 (they cannot say me nothing more). Geesh - my eq is probably 20.
But, I agree - beside that you can *learn* to be better on IQ tests, there is surely *the limit* that you cannot pass.
