i knew a lot of folks in engineering school who couldn't hack it and went one building over to business.
never met anyone who made the opposite move, for any reason.
I switched to and finished a BS in MIS from a business school because I wasn't enjoying my CS major. MIS offered me more project work, team building, and business skills. I followed it up with an MS in CS from the eng school at the same university.
Now you know of one person!
