Written qualifying examinations are given for each core sequence in the fields of quantum mechanics, statistical mechanics, classical mechanics, math methods, and electricity and magnetism. The exams are designed and graded by a committee of Physics faculty. The exam is offered at the beginning of each fall quarter. The exam is offered at the beginning of winter quarter for those needing a third attempt to pass.
PhD students are required to pass all five of the written qualifying exam areas within three attempts prior to advancing to candidacy.
MS students may pass four of the written qualifying exams as part of the comprehensive exam track to graduate.
Year 1 - before Fall quarter
Year 2 - prior to Fall quarter
Year 2 - prior to Winter quarter
Your first attempt at the written qualifying exams usually takes place during the two weeks before the start of classes. Exams are three hours each, spaced out every other day to give time for rest and study.
Continuing studends lead a series of group study sessions called Written Qual Bootcamp prior to the exams. Each study session is a few hours long, and specializes in problems for each Qualifying Exam. New students are encouraged to attend if available!
Exams are closed-book
Crib sheets are provided
Calculator
Water
Blank paper
Pencils/pens
Each section is a three hour, closed-book written examination, with one sheet of information (formulae, equations, etc.) provided.
You pick two out of three questions to solve for each exam.
Each question is worth 10 points maximum.
A score of 12 or higher on each exam is passing.
If you pass one exam area, you do not need to take that exam again.
You do not need to take all five exams at once - you can space out your attempts.
If you choose to space out your attempts, first-year students are encouraged to take
on their first attempt:
Classical Mechanics
Math Methods
Electricity & Magnetism
and on your second attempt:
Quantum Mechanics
Statistical Mechanics
Students with at most one or two failed tests have a third opportunity to pass their remaining tests at the beginning of the winter quarter of their second year. Students who fail any of the remaining tests at this third and last attempt, and students who have not passed three or more of the five written tests after two attempts can either transfer to the terminal MS program, or appeal to the Graduate Committee to continue on the PhD route.
In this latter case, the Graduate Committee considers whether there is evidence of likely success in the PhD program. The Committee evaluates and reviews the student’s progress towards candidacy, including performance in courses and progress in research, and recommends possible remedial coursework or an oral examination, or recommends that the student transfer to the terminal MS route.
Please contact the Disability Resource Center (DRC) for exam accommodations, like extra time, light or noise-sensitive spaces, exams in alternative formats, etc. You do not need to share confidential medical information with the Physics Department or faculty. Instead, meet with the DRC who will make recommendations to the department based on an evaluation of your needs.
Please allow 2-3 weeks to meet with the DRC and make departmental recommendations.
You may petition the Graduate Committee to waive a course if:
you score very high on the associated written qualifying examination;
you took the equivalent graduate-level course at your prior institution and obtained a satisfactory grade;
the course covers the material in the first-year courses syllabi.
Email the Graduate Committee Chair with your written qual score, unofficial transcript showing the equivalent graduate-level course, and a copy of the syllabus from that course.

Marion and Thornton, Classical Dynamics of Particles and Systems, (all chapters). This is an undergraduate level text, used in many universities in the junior year.
This is covered at an advanced undergraduate level. Suitable texts include those of Boas and of Arfken, in their entirety. This section tends to be somewhat unpredictable, but it is good to have a mastery of:
Elementary differential equations
Complex variables (particularly contour integration, and topics such as convergence of series, etc.)
Laplace transforms
Fourier analysis
You won't be expected to remember long formulas about special functions, but you might be given information (e.g. recursion relations, integral representations) and be expected to manipulate it to derive results.
Jackson, Classical Electrodynamics, esp. chapters 1-9, 11-14 (in principle, anything in the text may be covered in the exam).
