At my uni (UIUC), there's some technical issues with double majors. I had originally wanted to double major in cs and math, but that's not allowed, because cs is in the engineering college and math is in the liberal arts and sciences college. Since my college grants my degree, neither the engineering college nor the liberal arts college can grant me a degree with the two majors cs and math. I'd need to get two degrees: one from the engineering college and the other from the liberal arts college.
Although UIUC does offer a single "Math and CS" major through the liberal arts college to address this potential issue.
Are you able to use classes from one college to satisfy the requirements of the other college? For example, if you meet all the liberal arts requirements in one college I expect that they will count towards the other degree right? The fact that you cannot call it a double major is merely a technicality is it not (Although in my mind it is still a double major)? What does it matter if they are not issued by the same college? I still don't see the difference. At the end of the day you have two degrees.
Well, it is a bit of technicality I guess, but you're not getting two degrees with a double major. You're getting one degree with two majors (at least as far as I understand it). Getting a dual degree is actually getting two separate degrees. And there's a bunch of bureaucratic stuff you need to push through to get approved for a dual degree here (more than there would be for double majoring with two majors within one college).
As far as I know the requirements would count towards both degrees, though.
