Said test can also bias against the poor depending on how it's created. It can ask questions based on subtleties that only private schools/tutors have the time to cover or on life experiences that only upper middle class realistically have experienced. Neither system is perfect but I think the purely SAT approach creates too much unnecessary stress for high school students when there are other proxies for determining future success.
