University of Nigeria, Nsukka JAMB Aggregate Calculator
Federal institution · General JAMB cut-off: 180 · Two scoring methods available, see tabs below
How UNN's Aggregate Is Calculated
Your JAMB score is scaled to a maximum of 360 points. Your best 4 O'Level grades are converted to points and added directly (up to 360 points). A single O'Level sitting adds a +40-point bonus (two sittings: +0).
UNN uses a different method depending on whether Post-UTME screening is held that year — switch between the tabs in the calculator below to match your situation.
Only the 4 subjects written at UTME are scored. Formula: (JAMB x 0.9) + O'Level grade score + single-sitting bonus.
