A genius student who had never been taught those subjects wouldn't even know what the symbols meant. A mediocre student who had studied SAT-style questions for weeks leading up to the test would likely outperform a high IQ student who last solved those types of problems over a year prior.Standardized tests can be a great resource for assessing students, but they're not just testing for intelligence. Test-prep courses average increasing SAT scores by about 200 points. That's not because they're increasing the intelligence of the people taking them.
