Syllabi for Qualifying Examination Subjects

General QE Courses: Students must pass written exams in four out of the following eight courses: Algebra I, Algebra II, Complex Analysis, Real Analysis I, Differentiable Manifolds and Lie Groups, Introduction to Algebraic Topology, Mathematical Statistics, and Numerical Analysis.
Advanced QE Courses: Students must choose their academic advisor first, and then take exams in the courses designated by their advisor.
->> The students who enrolled by the spring semester of 2014: your GPA in 500-level courses (which must include at least three of the following: MATH 501, 510, 514, 520, 530, 551, 561) must be 3.5 or higher.
->> The students who have been enrolled since fall semester of 2014: At least 15 credits of 500-level-courses must be taken, and the courses GPA must be 3.5 or higher, and four QE courses must be passed within two years after admission.
