<p>OK, most of the ideas in this thread, I have seen before. One thing I discussed on another thread earlier tries to take all these into account. </p>
<p>My view is that colleges are making a conscious <em>choice</em> what kinds of students to accept. Notice that it's no accident that the average student going to a school like Harvey Mudd or Caltech is quite into math + science. Much more so than the average student at Stanford or Harvard. This is based on choice. </p>
<p>It is beyond clear that the SAT cannot measure success in the sophisticated college majors. SAT performance and mathematical ability in college cannot reasonably be linked, given the nature of math involves nibbling at large, thought-provoking theories, while the SAT involves closing off answers to questions and being careful. At best, there may be a correlation between success on the SAT and certain college success, because good students will try to game the SAT, and good students will also work hard in college presumably, on average. But this is a vague correlation.</p>
<p>The main issue is that private schools often are very reluctant to take too many students who're "purely intellectual." Not just high scorers, but students who really show some seriousness to their academics beyond just doing well in high school. For instance, the kind who'd succeed at the very intellectual small schools (e.g. HMC, many selective liberal arts colleges, Caltech, etc..). One can either argue they should take more of these, or leave the schools alone. I wish they took more, because the private schools also happen to have a wealth of academic resources many others don't.</p>
<p>The problem is, getting a good SAT + GPA may not be super easy, but may also not reflect very much about how good of a <em>COLLEGE</em> student you'll be. I know that there was very poor correlation between who was highly academically ranked in my high school and who really started to do great things in the respective major in college. [Compared to, say, lesser ranked students.] GPA is a game. I played it, and achieved a first rank in high school, and should know exactly how little that says about my academics in college. </p>
<p>My honest feeling is that if colleges do not want to more freely admit purely intellectual types [in favor of more diverse classes], then we can't say much; if they do, there needs to be a new and improved AP curriculum which really does things without watering things down.</p>
