Can you choose any subject test on the test day?

I need help understanding this. i am international in Singapore and I just signed up for bio e/m and math level 2 in october. But i want to add Spanish (without listening, only offered in november) and switch bio to physics. I heard that you can add or switch subject tests on the test day…is this TRUE? help needed thanks!

Yes. You’ll be charged for the additional test, of course.

In general, you can take a different test from the one you signed up for — the test booklet contains all Subject Tests available that day, so just take the ones you want. But there are some exceptions:

  • You can’t switch to a Language with Listening Test that you're not registered for, because they require special equipment.
  • If you’re taking any Subject Test with a special format (such as Braille or large-type test books), or in your school with school-based accommodations, contact Services for Students with Disabilities before test day to ensure that the right materials will be available.

If you decide to take fewer tests than you signed up for, just turn in your answer sheet before the next test begins. Remember, though, that once you start answering a test, you can’t decide not to take it — you’ll have to cancel all tests taken that day to avoid having it scored.

You can also add a test on test day, if it’s being given on that day. Just remember that the exceptions listed above will apply. You’ll be billed for the tests you add.

Very helpful, thank you!

I know when I took my subject tests I was allowed to pick any three of the ‘traditional’ subject tests, such as physics, math, literature, biology, chemistry, etc. A student didn’t sign up for spanish with listening and she wanted to take it, but the proctor said that she had to of asked for the listening part prior to testing day as the school didn’t have the equipment for the listening component.

@MrDiaz This is a great question – we recently covered this topic in a College Confidential article, which you can find here: https://insights.collegeconfidential.com/your-guide-to-sat-subject-tests
