What Makes a Course Last 4 Years?
Nigerian universities structure courses based on NUC (National Universities Commission) guidelines. Pure science courses like Mathematics, Physics, Chemistry, and Biology are typically 4-year programmes. They are structured into 8 semesters across 4 academic sessions.
Applied science and professional courses like Medicine, Engineering, and Pharmacy take longer. This is because they require clinical rotations, industrial attachments, or professional licensing hours.
Understanding this difference helps you pick the right path for your goals and timeline.
