Should they not make a test that the average undergraduate should not need to study for at all before test day which will test their general knowledge?
What on earth would such a test show?
Well, for those of us who thought that the GRE general test was such a test since it had high school level math, vocabulary, and logic problems and thus was actually easier than the SAT, it would show that some people wasted four years of their lives failing to pick up general knowledge things that will make every future intellectual endeavor less taxing.
