This is a great question. From my professional experience, most marketing roles require a minimum of a bachelors degree. And if you are looking to eventually take on an executive level role, a masters degree can be required to do so. That being said, you don't have to just focus on marketing as the sole aspect of your degree. Having a well rounded business understanding is extremely helpful in understanding the role that marketing plays in the overall business environment. At the same time as your career progresses and you achieve higher levels of responsibility, that business acumen will be very important to your success. You can also look at different areas of interest within marketing to specialize in a certain area. Or you can look at a dual major or major and minor options for specific areas of specialization. Marketing is a very diverse and exciting field and the more well-rounded your education the more options you may find available.
Best of luck!
