<p>I attached one because I had lots of ECs. I applied to a couple of all-girl schools (I would put them down, but since I am not sure if you are a girl…), Carnegie Mellon, Georgetown, Harvard, University of Chicago, Amherst, Stanford, Duke, UPenn, Princeton, and a state school. I got in everywhere except UPenn which wait-listed me. IMO, however, submitting a resume isn’t something that will make a huge difference in terms of getting in. It may tilt the scales slightly in your favor or it may not. Schools that get a huge amount of applications might not even look at them, according to my school counselor. They just don’t have the time to look at extra stuff.</p>
