PhD Preliminary Exams

The preliminary exams, or "prelims," are the examinations required by the department for admission to official candidacy for the PhD degree. Old prelims are available on-line.

Starting in 2018, the prelims will be administered twice a year: once in September (1st try) and once over the spring break (2nd try).  See “Exam Process” section below for changes to the eligibility criteria.

Exam Dates

In 2019, the first try of the prelims will be offered September 9-12, 10am-2pm:

  • Algebra: Monday, September 9
  • Real Analysis: Tuesday, September 10
  • Complex Analysis: Wednesday, September 11
  • Manifolds: Thursday, September 12

The second try for all of the prelims will take place during the week of March 23-27, 2020, 10:00am-2:00pm. (Exact dates will be announced in January 2020.)

Exam Process

These exams, four hours in length, are offered every year in the mathematical subjects treated by the designated core courses: algebra, real analysis, complex analysis, and topology and geometry of manifolds.

A student may substitute completion of a full three-quarter sequence of a designated core course, in which grades of 3.8 or above are received each quarter, for the passing of the corresponding preliminary exam. Only one exam can be replaced in this manner.

The written preliminary exams are given twice a year: once during the week in September that precedes the start of Autumn Quarter by two weeks, and once during the break that follows Winter Quarter. Each exam is four hours long, starting at 10:00 a.m. Only the students who have completed the corresponding year-long core sequence with a grade of at least 3.0 each quarter are eligible for the 2nd try.

The exams are written and graded by a committee, which delivers the results to the Graduate Program Committee.  The Graduate Program Committee then makes decisions about student performances. All students receive notes describing their performances by the end of the week following the exam.

The prelims are intended to serve as an objective measure of a student's mastery of basic graduate level mathematics.

Normally, students take several exams in September of year two, but students are welcome to attempt exams in September of year one.  A student is expected to pass two of the four exams, with at least one pass in either algebra or manifolds, by the September beginning the student's second year in the Ph.D. program. A student who fails to do so by the end of the second year may be advised to discontinue studies.

Students' experiences in the program and on the tests are important to us. If you have a temporary health condition or permanent disability that requires accommodations for exams (conditions include but not limited to mental health, attention-related, learning, vision, hearing, physical or health impacts), you are welcome to contact DRS at 206-543-8924 or uwdrs@uw.edu or disability.uw.edu. DRS offers resources and coordinates reasonable accommodations for students with disabilities and/or temporary health conditions.  Reasonable accommodations are established through an interactive process between you, DRS, and the GPC.   If you have already established accommodations with Disability Resources for Students (DRS), please communicate your approved accommodations to the GPC at your earliest convenience.

It is the policy and practice of the University of Washington to create inclusive and accessible learning environments consistent with federal and state law.

Exam Topics

There are four exams:

  • Algebra: Topics at the level of 402-3-4 and 504-5-6.
  • Real Analysis: Topics at the level of 424-5-6 and 524-5-6.
  • Complex Analysis: Topics at the level of 534-5-6.
  • Manifolds: Topics at the level of 544-5-6.

Each syllabus below lists certain topics that have appeared on the exams. This list is advisory only – it is intended to suggest the level of the exams, not to prescribe exactly the material that will appear. Past exams can be a useful source of practice questions, but a student need not master all material that has been covered on these exams. A student who knows the material in the syllabus and who has spent some time solving problems should do well on the exams.
