Send in all three. Those are great scores, and being that she’s STEM, that history score is a validation that she can be successful in humanities, as well. For students that I work with who are shooting for highly selective schools, I always use MIT’s advice, and say that anything with a 7 at the beginning is good enough, and in your D’s case, her Math II is perfect, so don’t be afraid to send the history.
My own two older sons each submitted 3 scores, and literature for both of them was the relatively weaker scores at 730 and 710; nonetheless, I think those scores were fine, and they both were admitted to highly selective schools (MIT, Penn, Princeton, etc.).
