ACT also. But just because they are convenient does not make them the best measures to compare applicants across varying high schools. Indeed, both UC and Harvard found that achievement based tests (SAT subject, and AP for Harvard) are better predictors of college performance than SAT or ACT (which they found worse than HS GPA). But with the SAT and ACT having incumbent status, using the other tests tends to create barriers against those from less advantaged backgrounds, where they may not know that the other tests may be useful.
