Frequently Asked Questions
How is semester GPA calculated?
Semester GPA = Total Quality Points ÷ Total Credit Units. Quality Points for each course = Grade Point × Credit Units. Sum all quality points, then divide by total credit units.
What is the difference between GPA and CGPA?
GPA (Grade Point Average) is calculated for a single semester. CGPA (Cumulative GPA) is the weighted average across all semesters completed. Use our CGPA calculator for multi-semester calculations.
How many credit units are typical per semester in Nigeria?
Most Nigerian university students take 15–21 credit units per semester. Courses are typically 2, 3, or 4 credit units. Lab courses may carry additional units. Aim for 18 credit units if your workload allows.
What GPA do I need to avoid academic probation?
Most Nigerian universities place students on academic probation if their CGPA falls below 1.0 (on 5.0 scale) or 1.0 (on 4.0 scale). Some universities use 1.5 as the minimum satisfactory academic progress threshold.
Can I calculate GPA with incomplete grades?
Skip any course with an incomplete or pending grade. Only include courses with final grades. Your GPA will be recalculated when the final grade is entered.
