If I'm interested in majoring in finance at MIT, is it okay for my whole application to reflect my interest in just finance, or do they want to see interest in science and math as well?
Colleges want applicants with “spikes” in their talents (rather than being well-rounded, you specialize in one particular interest). This means that if you are interested in finance, you only really need to show that interest. Of course, if you have the option to do a really amazing science extracurricular, you can still do that, and it will still be a point if interest. However, if you can substitute that for something to do with finance, that is even better!
