Absolutely!  Previous majors—including those who have completed thesis research or even a second major—have taken advantage of the exceptional study abroad opportunities offered through the college.  If you are considering studying abroad, you should plan ahead as early as possible to make sure you are able to complete the courses you need during your semesters on campus.  One issue can be that it is difficult to find sciences courses abroad that fulfill our requirements, although students have been able to get credit more easily for science courses at British and Australian universities and at Jacobs University in Germany.  We recommend talking with a faculty member in your prospective major early during your planning process to help you construct a reasonable plan that includes your desired study abroad.
