What’s the ideal composite ACT score for an international student applying to Harvard?
You should aim for a 35 or 36 to give yourself the best chance of admission. Harvard’s average composite ACT score for admitted students is a 34. The 25th percentile score is a 32, and the 75th percentile score is a 35. That being said, if you’re an international student, you may have a bit of leeway on the English and Reading sections. I’d still encourage you to shoot for at least a 32 or 33 on those sections.
