Can I combine my highest EBRW and Math subscores from different test dates?

YES! The SAT introduced score choice in 2009, granting students the ability to combine their highest Math and EBRW (Reading + Writing & Language) scores, creating an automatic "superscore".

‍

For example, let's say John scored 720 Math and 660 EBRW In October, and then 690 Math and 740 Reading in December. If John elects to send both scores to universities, what those universities will see is a composite score of 1460, comprised of the 720 Math from October and the 740 EBRW from December.

This policy is great for students who perform somewhat inconsistently from test to test, and it gives peace of mind to those students who have already achieved their target score in one section.
