Rabi Scholar vs. Vagelos Scholar vs. Caltech

<p>Hi,</p>

<p>I'm having trouble with decisions. I was invited to the Vagelos Scholar program at UPenn, but I've also been named a Rabi Scholar for Columbia, gotten admitted to Caltech, and gotten Berkeley Regents. My major is Physics for the first 3, and EECS for Berkeley. Any advice? (I'm interested in not only Physics, but other sciences, Engineering, and possibly Economics, Business and Finance). Thanks!</p>
