Since the UC system eliminated the SAT and ACT and leaned almost entirely on high school grades, UCSD reports a nearly 30-fold increase in students arriving without middle-school-level math skills — the equivalent of roughly a 3,000% increase. The university has since had to redesign its remedial courses to reteach fractions and elementary arithmetic.
