Any student applying to California State University (CSU), University of California (UC), the honors program at a community college, certain merit-based scholarships, or private universities and colleges, should take either the SAT Reasoning Test (which tests verbal, math, and writing abilities) or the ACT, which tests verbal, math, social studies, and science reasoning. An overwhelming number of colleges and universities will recognize either test. If you have the money and the time, take both. Additionally, for the UC and top private universities, applicants must take two Subject Tests in two different subject areas: history/social science, English Literature, mathematics, laboratory science, or language other than English. Registration can be done online.
Reminder:
Tests must be taken by December of the senior year. Private colleges have other deadlines and test dates.
