<p>a 3.3/3.4 is really bad for duke and a 3.02 would give you zero chance. A 28/29 would also hurt you. And even a 30 might hurt you and at the very least would just be approaching average. You have everything else in your favor and your ECs are outstanding, but overall I would say that your grades have killed you. Especially because you are not taking a lot of hard classes, at least compared to the average Duke applicant.
You have a very tiny chance, but frankly I would focus on other schools, because with your EC’s, at a school where your academics are average you will be a stand-out and could receive a lot of money.</p>
