Will an A- (3.7) GPA be a big no-no for Penn admissions without a hook?
How well are your essays written? How are your testing scores? How rigorous were your courses? What school are you applying to and in what area? Dude, you can make a hook. Give them a solid reason why you need to be there and how you’ll benefit the Penn community. I’m sure they’ve taken 3.7 kids before, but that other stuff should be there.
No, 3.7 is on the lower end but still fine. Anything below a 3.5 would be a no-no.
