Ph.D. Qualifying Exam
Each Ph.D. student has to take (and pass) Ph.D. qualifying exam after finishing his/her required course work with 2,75 GPA. Ph.D. students who have the conditions must take CMP702 Qualifying Exam course in same semester. Ph.D. qualifying exam consists of a written part and an oral part.
- Ph.D. Qualifying exam is offered each semester in December and May. The examination committees are organized in April and November.
- The written part contains 10 subject areas. The questions in the written part are at the undergraduate level and can cover the topics that are given under each subject area. The undergraduate courses related to each subject area are listed below wıth the topics that are covered these courses.
- There are two questions from each subject area, and the student is asked to attempt only one of the questions from each subject area. Each question is graded out of 20 points.
- The written part is given as two sessions on two different days. (180+180=360 minutes).
- The oral part can contain the questions from the subject areas of the written part, the subject areas related to the candidate’s Ph.D. thesis area, and the candidate’s Ph.D. thesis.
- The students are expected to be successful at both written and oral parts of the exam.
Written Part
- The written part is given as two sessions and contains a total of 10 subject areas.
