Minor in History
It's easy to add an undergraduate minor in History to your academic plans. The minor requires 5 upper-level courses in history (3000 or 4000 level). They can be about any geographic region or any time period, so you may have already fulfilled most of the requirements.
The skills you build in history courses can be useful preparation for law school, graduate school, and professional careers. Plus, a history minor will make your resume or transcript stand out.
