The SAT Subject Tests (formerly SAT II) measure your knowledge and skills in particular subject areas, and your ability to apply that knowledge. All Subject Tests are one-hour, multiple-choice tests with various formats. Students can take one, two or three exams on the same day.

The best time to take the SAT Subject tests in when you complete the highest level course in the subject you plan to take. However, keep in mind that only a small number of colleges and universities actually require SAT Subject exams.

Some colleges specify which tests are required for admission or placement; others allow applicants to decide. Some colleges will accept the ACT instead.

After you've decided which exams you plan to take, plan ahead. If you take certain AP classes, as a freshman or sophomore, consider speaking with your counselor about taking the test at the completion of the course.
