Boston University Dual Degree

I’m a prospective student at Boston University and was wondering if doing the dual degree program in COM and Questrom is a good idea. I applied to COM mainly because I heard that BU’s COM program is pretty good and I am somewhat interested in the advertising industry, but I am more knowledgeable in areas pertaining to business. The reason why I didn’t initially apply to Questrom was because I heard that grade deflation is severe there and I wanted to maintain my GPA. Is it hard at Boston University to apply for a dual degree at the school of your choice?
