Sheesh...
I'm not even sure how double-majoring would work. Could someone educate me on it? Is that even feasible?
You can totally double major. I know people who have. It's a lot of work. It might take five years of undergrad, rather than four. But, some people do it in four.
Also, it's easier to double major, if the two majors have overlapping requirements and pre-requisites: Say, for example, physics and mathematics.
