SAT Subject Tests: Minimum score to send to colleges?

Should I send all scores (600+) or only those above 700? I am applying to some top schools like the Ivy’s, Stanford, and Notre Dame.

Here are my scores:
Math 2: 780
Physics: 730
US History: 730
Biology E: 720
Biology M: 670
Chemistry: 640

Thank you for answering.

Well for ivies, the general rule is send anything above 700.

Jesus, why did you take so many subject tests??!
I would send Math 2 and Physics
For top schools, anything around 750 is competitive, but 700 is the absolute minimum IMO

May have been better to focus on maybe two or three subject tests and do better on them instead of taking 6 and not doing as well
