<p>I agree with the person who said take some classes first. They won’t let you officially apply to be in a dual/double until the end of your freshman year anyway (because before then it doesn’t even matter). But for something like Economics?.. You really need to take a few courses in it before you decide to make it your major. I’m a econ major, and I know a LOT of IA majors who had to take some econ for a requirement, and they wanted to cry all semester. Not saying IA majors can’t do econ, I’m just saying that it seemed like people who didn’t take econ because they *wanted *to take econ ended up much more miserable (although their grades were fine). So you shouldn’t commit yourself to it unless you are sure.</p>
