There are no “useless” college courses. You need to figure out major you most like. Remember to consider the advanced level courses that are a part of the major. Do you want that much theoretical math? Likewise, once you get beyond the intro economics it may be fun for you. I definitely agree that economics is not a business major, it is a social science. Ditto on the econ/calc requirement.
OP- look at the courses at the advanced level you would take- required and recommended- for proposed majors. Do not worry about having so many credits you may as well continue with one. Those upper level courses may not be what you want.
