Ph.D. students must complete 11 one-semester graduate subjects (132 credit hours), exclusive of thesis, with grades of A or B. At most one of these subjects should be a reading course. Harvard math graduate subjects may occasionally be used, if taken for credit. One relevant advanced undergraduate math subject may be used, and relevant graduate subjects from other departments may be used if approved by the relevant Graduate Co-Chair. Note that subjects taken under the graduate P/D/F option cannot be used to fulfill this requirement.
Students are expected to maintain at least a B+ average in each semester. Students in Applied Mathematics must satisfy an additional breadth requirement.
