I believe there to be a high correlation between IQ and standardized tests not requiring specialized knowledge such as SAT, LSAT, GMAT. My percentile scores in these measures have remained more or less stable.
For example, even though I took the GMAT with under a year of formal college instruction, I scored in a similar percentile as my SAT. Given I was competing with college graduates with the GMAT, the percentile should have dropped. But it didn't.
Also, my split between different subjects has remained unchanged. Even though I've taken far more math classes than English classes, I continue to score in a similar (high) percentile in English and a similar (lower) percentile in math.
These trends have held true with my friends as well, and a correlation is supported by studies. What I'm saying is not that someone with a lower IQ can't score well on standardized tests, but it's going to take preparation. On the other hand someone with a higher IQ can most likely just walk in and get the score they want. You know where you stand, and I'd recommend to plan appropriately.
