How do I take an SAT Subject Test if my school doesn't offer them?

Like I said in the title, my problem is that my high school doesn’t offer SAT Subject Tests and I want to take a couple so I can apply to college. Where can I go or who can I contact so I have a chance?

The SAT subject tests are administered like the SAT tests. You need to find a test center near you.
