Posted below are old comprehensive exams for the PhD program in Math going back to 2001. The answers to the post 2015 exams are posted on the School's Intranet. The names in the brackets refer to the writers of the exams (who also graded the exams), and the numbers indicate the ratio of students who passed the exams. Prior to the Spring of 2015, comprehensive exams were offered only in two subject areas.
