Transfer from UVA to Princeton or MIT

Hey everyone, I'm currently a first year at UVA School of Engineering and I have a 3.9 GPA, I'm thinking of transferring to Princeton or MIT not just because of the name or anything, but because of pursuing a project that I think I can continue at these places. I'm currently studying CS as my major and doing a minor in Physics and Materials Science Engineering. Any advice on what I should do on the essay portion of the common app for transferring adn any general advice would help.
