@lb43823 No, do your own research and stop asking people here things you can easily find out on your own.
And you asking silly and elitist questions like “Do you think in the future Duke’s acceptance rate will be even lower, and it’ll get more selective?” shows me you lack depth and are only looking to see how prestigious Duke can get within a certain time frame.
Go get an internship or something or make some new friends rather than worrying about how selective Duke can get.
