Graduate School students in PhD and Master’s with Thesis programs who have not yet transitioned to the thesis stage must NOT enroll in Master's Thesis / PhD Dissertation course (Tez dersi). This includes, for example: Students who still have not completed their course requirements; PhD students currently in the qualification exam stage; and PhD and Master's students who have not yet submitted their thesis proposals. In contrast, Academic Specialization (Uzmanlık Alan Dersi) course must continue to be taken every semester until graduation.
