Do most students do a thesis or a project or a comprehensive exam?
The best answer to this question is that it does not matter what most other students do. The options exist in order to cater to the needs of a range of students. For example, students who wish to go on for a Ph.D. should do a thesis. Students who need a TR internship to sit for the national examination must do an internship. Projects often are a good option for students currently working in the field; often their place of employment needs a survey, feasibility study, or some other major undertaking that might also serve as a project. In general, however, about half of our graduate students do an internship and about half do either a thesis or project.
