So when you’re applying to UCs, do you have to submit all of your SAT Subject Tests?
Score Choice for SAT Subject Tests at UCs
SAT Subject tests are recommended for some majors at some campuses (check the UC’s general application pages for details) but they are not required. They are there to help you demonstrate mastery of a field, and may strengthen your application. Including them is optional for the UC system.
So even if you have taken the same subject test twice, you only have to send the higher score, right?
Technically, you do not need to send any subject test scores at all.
Correct. You can send some/all/none. Your choice.
