It's never too late to pursue your interests, even if it means extending your time in school. Of course, I think you should not make a decision without investigation. You might consider taking a science course for non science/engineering majors. Those types of courses usually limit the amount of math required to appreciate the subject. You should also consider talking with someone in industry .. and learning what you might be most interested in. Finally you may not have confidence in your math and science skills at this point but if it is your passion you can always develop those skills and the confidence associated with being able to leverage them. Please keep us posted on your path and progress.
