Not sure about the SAT, and maybe the test has changed since I took it, but the ACT was mostly a knowledge & skills test. Math: did you pay attention through at least high school trig? Reading: how literate are you? English: how well do you understand the mechanics of SWE? Science: Can you read intentionally-shitty graphs to extract the correct information (yes, seriously, that's what it was, not anything to do with science, really) and so on.
