How can Barbara solve this problem?

Barbara is a sophomore college student. She needs to declare her major this semester, but she cannot decide between psychology and economics. She has really enjoyed the psychology classes she has taken thus far, and there are a few classes she would love to take that are only available to majors. However, her GPA is slightly higher in her economics courses. She thinks she would ultimately prefer a career in business and is considering applying to MBA programs after undergrad. She is somewhat apprehensive about the course load associated with a double major. How can Barbara solve this problem?
