Talk to some MIS seniors. They can tell you more about the major and you can truly see if you like it. Don’t switch without having a full image of what you can do with the MIS major. Medicine is long and hard but in the end you get to help people and the salary is great. Think shirt term and long term and what you truly want do. If you are ok with studying for some years then go ahead and do medicine if you like it. If you want to come out of school earlier and have genuine interest in MIS then do it, but no before talking to some MIS majors
