It has been a while since I was in college but the first couple of years are generally spent taking required courses so you have plenty of time to explore your career interests and make a decision on whether the major you have picked is truly the one that will lead you to the career you desire. My college provided assistance with career exploration. I took a personality test, and test to determine what my interests are and what types of jobs I would be interested in. It really helped me decide what I wanted to do for a career.
Jeanette recommends the following next steps:
That's actually okay! (usually). There are a gazillion jobs out there that will accept any degree. They just want to see that you have one. There are many degrees that are transferable into many fields. But, this is, of course, within reason. An accountant won't usually become a band director, for example. But, I've seen people with chemistry degrees go into banking. Part of it will depend upon what other work experience you pick up, and your ability to show the applicability of your experience and education for the position you are applying to.
All that being said, what do you want to major in? Do you have a general idea where you are going? Let me know, and we'll see what's out there!
