Honestly, it’s probably better to get a social sciences major from a brick-and-mortar campus than it is to get a business degree from an online for-profit college.
Why don’t you just minor in business or take a lot of classes in it? You can still do the social sciences major so you can graduate in 4-5 years, but take as many business classes as you can, take some statistics/finance/economics or whatever and then do some business-related internships in the summer.
