A D7 in Economics is considered a pass, but it is a low grade. Your chances of remaining in the Public Administration course at UNN depend on several factors: 1. UNN's Specific Requirements: Each university and department has minimum O'level grade requirements for admission. You need to check the official UNN admission requirements for Public Administration for your specific admission year. Some departments might require a credit (C6 or higher) in relevant subjects like Economics, while others might accept a pass (D7, E8). 2. Other O'level Grades: Your overall performance across all required O'level subjects (e.g., English Language, Mathematics, Government, Literature, etc.) is crucial. If your other grades are strong, a single D7 might be overlooked, especially if Economics is not considered a core subject requiring a credit. 3. JAMB and Post-UTME Scores: Your scores in the Joint Admissions and Matriculation Board (JAMB) exam and the university's Post-UTME screening also play a significant role in your aggregate score for admission. Recommendation: The best course of action is to directly contact the Admissions Office or the Department of Public Administration at the University of Nigeria, Nsukka (UNN). They can provide the most accurate information regarding their specific admission criteria and whether your D7 in Economics affects your status in the course.
