Who should take the SAT subject tests?
Not all colleges require students to sit for these tests and of those that do some require students to take two subjects and some require three. Some courses have specific requirements (for example, students might be asked for Mathematics Level 2 and Physics if they are applying for Engineering). Always check the specific requirements from the college website. A student can sit for up to three subject tests on the same day. It is not possible to sit for the SAT Reasoning Test and SAT Subject Tests on the same day. In many ways these tests are more straightforward than the Reasoning Test: they are based directly on the high school curriculum and the questions are not tricky.
