Cal Schools May Nix SAT In Admissions Process

An unnamed correspondent writes: "The University of California school systems is considering to stop using SAT scores in college admissions. Story at Yahoo." The usual double-edged sword here: the SATs, ACTs and similar tests may be close to worthless, but other factors (like how GPAs ^[?] are calculated and weighted) varies wildly from school to school. (What might a GPA of 3.9 at Stuyvesant High be worth elsewhere, for instance?)
