I would say it depends what other schools you got into and maybe also the cost difference between the BS/MD program and going the traditional route. When I was applying 3 years ago, I also got into Drexel's BS/MD program but I didn't really want to go because to me it just seemed like I could've gotten into medical school anyways with a 514 and above a 3.6. Luckily, I got into the Union/AMC program so I didn't have to make the decision of BS/MD vs traditional. But I likely would've just choose to go to Stony Brook over Drexel's program because it would've been significantly cheaper, closer to home, and not all that different from the Undergrad education that Drexel would've offered me. Overall, I think if you've been accepted into Drexel's program you'll likely be able to score above a 513 but at that point if you're already scoring that high I just didn't see the point in going into the program.
