What would be considered a good SAT subject test score in BioM, US History, and Math2 for schools like Yale or Harvard?
As our article on SAT Subject Test Scores and the Ivy League states, a good SAT Subject Test score should be in the top 80th or 90th percentile of all test takers (usually in the upper 700s).
For Bio-M: 750 at the lowest (and a 780 or above to be in the top 90th percentile of test takers).
For US History: 740 at the lowest (and a 770 or above to be in the top 90th percentile of test takers).
For Math 2: An 800 is an 81st percentile score, but a 750+ score would probably still be okay (particularly if you have higher scores on your other two subject tests).
