The more selective the school, the more “random” it can appear. When you are dealing with acceptance rates of less than 10% (be it for the school or for a specific major), and you are competing with a pool of applicants just like you, all very qualified, 90% of them will be rejected. Applying to more of them, does not increase your chances.
That said, why does somebody get into Harvard, but not Yale? Beats me.
Maybe you’ll get some good news tomorrow. You could do worse than the Rutgers Honors Program.
