Score Choice SAT Subject Tests

I took three SAT subject tests in one test day, and I don’t think I did well on one of the tests. Can I not use the four free score reports, so I don’t have to send that one bad score? What are the score choice policies for subject tests at Ivy League schools? Or alternatively, I did not pay for the third test and took the test I did bad on without registering for it. Can I refuse to pay and get this specific subject cancelled, or will they delay the rest of my scores?

Every single college in the country, other than Georgetown, allows score choice for Subject Tests.

But if you use the free report they send all from that day.

You cannot cancel a single subject test, only all from the same day.
