Harvard University does not have a strict minimum GPA requirement for undergraduate admissions. However, admitted students typically have very high GPAs, ranging from 3.8 to 4.2, with an average GPA of 4.18. To be competitive, you will need nearly straight As in all your classes. It is important to note that Harvard considers the entire application, so a weak GPA can be compensated by other factors such as extracurricular activities, essays, and recommendation letters.
