Registering for Subject Tests
You can register for SAT Subject Tests in the same way as the SAT Reasoning Test--through SAT Online Registration. You can take up to three Subject Tests during the same test administration.
If you have not previously registered for an SAT Reasoning Test or Subject Test, simply select "SAT SUbject Test" on the "Choose Test" screen.
If you have previously registered for an SAT Reasoning Test or Subject Test, please click the "Change to SAT Subject Test" link. You will then be prompted to select "Continue to Full Registration."
You can use EZ Registration only if you're registering for an SAT Reasoning Test. If you click "Continue to Full Registration" you'll go to the full registration process, but you'll still have a head start with any previous test information and any information you've changed here.
