FWIW: Google “ACT Score and GPA Correlation” and you’ll get a table of national averages that look something like this:
The Admissions Officers at Harvard – or any US college for that matter – are going to look at your perfect 4.0 GPA and your 27 ACT and think something is terribly wrong, as your test scores are way out of sync with your GPA!
As such, Admissions is going to wonder:
(a) Did you have a bad day when you took the test?
(b) Is their grade inflation at your high school, as a student with your GPA should have scored much higher on the ACT?
(c) Can you handle the reading and work load at Harvard?
None of that is good. If you are interested in ANY TOP 20 US COLLEGE, you. must retake the ACT and score greater than a 32!
