Qualifying Exams (Joint Program Examinations)

All Ph.D. students must pass two Joint Program Examinations. One exam covers Mathematical Analysis (MA 640 and MA 641). The other exam covers Linear Algebra and Numerical Linear Algebra (MA 631 and MA 660). Each exam is three and a half hours long.

""Master's degree students who are not planning on writing a thesis and who have passed the Joint Program Exam will not be required to take the final oral examination for the master's degree.

Scheduling an Exam

The examinations in Mathematical Analysis and Linear Algebra are given during two periods each year (one in May and one in September). During each period a student may take one or both of the exams, subject to the following restrictions:

  1. each exam may be attempted no more than twice, and
  2. students may participate in exams during no more than three periods.

Any student considering taking an examination must meet as soon as possible with the Graduate Student Advisor, Dr. Roman Shterenberg, in University Hall 4035 for scheduling information, advice, and information.
