From my experience with business and marketing classes, I would say those majors are pretty easy.
My major is in art, and people don't realize the time commitment needed to do well in those classes. For about a year straight, I was at my school until 2/3am every day working on pieces.
I wish I could have just sat in the library and wrote some papers.
Currently studying Metagenomics for my post graduate which is one of the newest and advance study in biotechnology. It's f*cking hard even in my university only one professor has done this but he's barely has the knowledge about this.
I'd wholeheartedly give a computer related degree (specially CIS) my all, but I'd rather kill myself than studying history/religion/philosophy/sociology
