I was but left it and ended up in a different degree(s).
Marketing itself was interesting and like has already been stated mainly common sense. I originally wanted to write commercials etc and thought this would be a way to get into that...it isnt, that is normally contracted out to external agencies, i had some meetings with people who do that here and the majority of the people they have writing and designing their advertisments were actually art grads, not business majors.
With regards to math, all business degrees have a fair bit actually, for our program we had to do 2 stats classes, calculus, accounting has a lot of math and so does finance. All of these are required, all of these drain your very life out in front of you. Like they said above, the difference between any business degree is really only 3 classes so you will have to do all the other breadth shit that sucks to graduate with your marketing degree, and that was one of the contributing factors that made me change programs.
Personally, I found business restrictive, it mattered what kind of shirt you wore, (fyi ski shit is frowned upon) it mattered what bars you went to and who your friends were. I am not down with that shit and found that business was too ruthless and too restrictive towards my creativity. I dont need a business degree for my planned carreer so I switched my major (I was a double major so it wasnt that big a deal for me to switch) now I will be graduating with 2 full degrees and am much happier. I look forward to going to class and dont only attend the minimum to pass, my GPA improved to.
Try it you can change and, overall, do something you like. These are the best years of many peoples lives, dont waste them training to be another corporate drone in a cubicle if you dont really want that future.
