Chance at darmtouth with low act

I am applying ED to the class of 22
I have a high gpa 99.88
but my Act is a 31
I have good SAT subject test scores
My father is a Dartmouth alumni

I know that dartmouth is more holistic than other ivies. Will a test score of 31 be enough if the other aspects of my application are strong?

I’m no admissions officer, or anyone with an extent of knowledge. But considering you have a stellar GPA, good subject tests, and are applying ED as a legacy, you have a good chance. 31 isn’t that low, and if you think it’ll be worth it to take it again then go for it, but if not, don’t sweat it. You didn’t mention any extracurriculars, but as long as they’re strong, I’d say you’ve got a fighting chance.
