The term 'Graduate School Grillings' refers to the process of Orals, which is a five-letter word. Orals are an important part of the graduate school experience, as they are a comprehensive examination of a student's knowledge in their chosen field. During Orals, students are asked questions by a panel of faculty members and must demonstrate their mastery of the subject matter. The results of the Orals determine whether or not a student is allowed to continue in their program.
