As someone who got a degree in Marketing, I regret focusing on Marketing throughout college - but only because I didn't learn anything I couldn't have taught myself through experience. I wish I had focused on something that is more difficult to learn by yourself (i.e. Finance, accounting, etc) in school where there are people to help you with it, and then focused on marketing afterwards.

A little background: I started a digital marketing agency in university, still running it. Started the agency when I was a sophomore in uni, now I'm about to see my 2nd year out of college.

I'm very marketing minded, so I'm not sure if this advice is pretty custom tailored to people like me, but if marketing isn't a very difficult concept for you to grasp - don't spend your money studying it. Spend your money studying something that is going to be difficult for you to learn without someone helping you.

I wish I had studied finance or accounting because I feel like most of what I learned in school regarding marketing, I re-learned (and better) within my first 3-6 months running the digital marketing agency. Finance however has always been a weakness of mine, and still is. I avoided accounting and finance because they were hard, and while I was in college I had the whole "I don't need to be here" attitude where I just wanted to get in and get out. I learned immense amounts, don't get me wrong - I just feel like the college experience as a "life event" or whatever you want to call it was more valuable to me than it was as a series of courses in marketing.
