Can I do a secondary field?

Yes, as long as the secondary field is substantially different from your focus field in Social Studies. Harvard College allows only one course to overlap between the primary and secondary fields, and Social Studies counts all social science and history courses for concentration credit. But students can petition to “unconc” (not count) courses in one of these departments at the beginning of their senior year, as long as they are submitting a focus field that does not overlap with these courses, and as long as the discipline or disciplines they are covering in their thesis does not overlap with the courses they seek to “unconc.”
