One of the challenges of taking classes in marketing in college, is how quickly the landscape of the marketing world changes. The textbooks they buy are quickly outdated. In an internship, you'll look more with the hands on real world experience due to the fast pace environment, real world challenges, and every growing technology and partnerships, than you will in a semester of college. Not that school is bad, but the reality is, you cannot learn the real world skills you need just in a classroom. Getting that real hands on experience is crucial to your future success.
