You may not be good at coding but certainly need some interest in it to pass your course. You also must have a strong interest in technology and business. The best part of this degree is that you have the numerous career options. You are not tied down to a single path. This may also seem like a negative aspect as the degree is a little vague. MIS, however, is about navigating business (management) with technology (information systems), so to advance in your career you will need some understanding and knowledge of coding. And since, technology keeps changing, you must have a natural interest to keep up with both aspects of the degree (business as well as technology).
You will survive even if you are not good at coding. Just don’t go for career options that corner you to the technical side.
In conclusion, you don’t need to be good at coding to pursue MIS. But you must have an interest in technology and business to make good use of your degree.
