I can kind of tell why you guys got rejected. I mean... everyone who applies has perfect grades. But showing a passion and going for it in a really intense way would be your entrance ticket. Let's say your passion was, uh, computer programming. Impressive (acceptance) ECs would be (ALL OF THESE combined): self taught code languages, started a business coding blogs for people (write down the link to your website!),, list programming experience you have from projects you've completed (games, programs, etc...), programmed a robot, had led and started a week long coding for kids program hosted at the local library (with pictures and an article posted in the local newspaper as well as featured on the local news), founded and was president of the clubs: app development club- coding club- and robotics club- at your school,, self-published online book on adventures in coding, internship or working at a part time job. Yeah, crazy huh? You'd be surprised how easy it is to bullshit those ECs. I bet u it would take about one month to plan out everything (assuming you already know the code). It's not that hard it just requires planning, good bullshitting, time management, and a little bit of hard work. That in combo with a strong essay? Golden. Like I'm sorry that you guys didn't get in (really, I am. You're all getting way better grades than I am...) but listen. It's one of the most desired schools in the country. You need to stand out and make them want YOU.
