Sending SAT Subject Tests

My son took subject tests because they were required (“strongly recommended”) for another school - W&L. He didn’t really have time to prepare for them and took them late (November?), so no chance to retake. He took 3 on one day - Math 1, Math 2 and US History. Received scores of 700, 710 and 600, respectively. Never took honors or AP US History course, partly explaining his low score on that one, but needed two subject tests in different subjects for W&L, and thought he would fare worse in the other subjects. His SAT I scores are CR 620, M 760 and W 760.

Any suggestions on what two subject tests he should send to UVA? Both math scores, or Math 2 and US History? They claim they you can send in any two you want. Really struggling with this.
