When it comes time to determine which SAT Subject Tests high school students should take, it’s always a good idea to confirm which tests are required or recommended by specific colleges. In some cases, universities have strict requirements about the number of Subject SAT Tests that must be taken. Other colleges require specific SAT Subject Tests that must be taken. Still other universities may require SAT Subject Tests, but don’t mandate the specific subjects. Finally, there are also schools that will accept SAT Subject Tests, if they benefit an applicant, irrespective of the subject.
