Ph.D. students must complete 8 one-semester graduate subjects (96 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. With prior approval of the Graduate Co-chairs, one relevant advanced undergraduate math subject and relevant graduate subjects from other departments may be used. 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.
