Should I send my Math II Subject Test to Columbia, Vanderbilt, and USC?

The only schools I’m applying to on the Common App are Columbia, Vanderbilt, and USC for Civil Engineering. All three schools don’t require subject tests, but I feel like it’s not going to look good if I don’t submit mine. I got a 740 on the Math II test, which is only the 57th percentile. I only got 610 on Physics, so I know I’m not submitting that one. Is 740 worth it to submit?

Also, I’m not sure if I would need to submit all of my scores, including the SAT I scores. If I submit the subject test score, would I have to submit my SAT I scores? I believe they all allow score choice, except Vanderbilt states that they encourage you to send all scores. I was only going to submit my ACT score since I got a 32 compared to a 1330 on the SAT.

Should I submit my Math II subject test or stick with only submitting my ACT score?

Thank you.

You got 57th percentile among a pretty select group of kids. Remember, a perfect 800 is like the 79th percentile for that test, correct? In other words, the Math II subject test isn’t particularly good at separating among the top testers. Schools requiring subject tests do tend to look for a threshold score more than a percentile.

IIRC, subject tests can be clicked separately from SATI on Score Choice.
