Wrote my essay on politics. Want to apply for BSE

I’m applying for Princeton through Questbridge. I know I want to do engineering in college, but I wrote my essay on politics because that prompt fit me better than the other ones.
With that in mind, should I put my major as Undecided or just leave it as BSE before submitting?

@WhatNameIUse does applying through QB excuse you from the Princeton supplements?

Applying BSE with a political essay is fine. It might make you seem like an interesting person.

@psywar No; you still have to do the Princeton supplements. (On an unrelated note, QB does excuse you from Yale’s ComApp supplements.) In any case, the OP has already submitted. Good luck!
