In India, a three-year bachelor's degree/PG has become the recognized standard. In order to complete a three-year bachelor's degree/PG program, students must study at least 15-20 different subjects and pass a comprehensive exam in each subject. A thesis project in the student's major area of study must be completed by the end of the third year of study. In contrast, a single sitting degree must either make an attempt at a program curriculum that includes each of these 12 subjects in just a year, or must compromise degree requirements by teaching fewer subjects or watering down the exit exams. Neither of these options is considered an acceptable alternative, leading to the discontinuation of single sitting degree programs.
