<p>Some prep. is needed to do well on SAT / ACT. But these tests are very low level, and this needs to be understood. As an example, some adbanced math kids neglect the fact that math on these tests is primarily middle school. Being advanced, they neglect to prep. for it and get punished with lower score than anticipated because material simply needed to be re-freshed. Math is so easy to be improved by prep., many do not take advantage of this fact. No need of some fancy expansive classes. Just take practice math sections, preferrably timed and go over every single incorrect answer. High math score is quaranteed. Other secitons are not that possible to prep. aside from getting familiar with format and taking few priactice tests. Not much anybody can do about their personal way of reading and writing. All of that has been done in English class, not much more you can do. I do not know much about IQ, I know for the fact that k - 12 is so low level that anybody who work hard enough and turn their complete homework on time is pretty much quaranteed straight A’s, no brilliance is required for that, we are NOT dealing with the rocket science here. The same pretty much goes for most of UG programs. There are few that are more challenging, primarily engineering. If we are talking about real challenges, then we need to discuss Grad. schools (again, not all MBA programs, as one example, would be that challenging).</p>
