Federal universities

State universities

Private universities

Most private universities follow the NUC standard scale, but a few — like Babcock — set a higher A-grade threshold. Always confirm your specific institution's exact boundary.

NUC 5-point grading scale for Nigerian universities

This 5-point scale is the NUC standard used by most federal, state, and private universities. A small number of private universities — Babcock University and Adeleke University among them — require 80% rather than 70% for an A grade. Always verify your faculty's official grading policy.

Degree classification thresholds

These thresholds are standardised by the NUC and apply across federal, state, and private universities. First Class is highly competitive — fewer than 5% of graduates typically achieve it across most programmes.

How CGPA is calculated, worked through

Nigerian universities use credit-weighted CGPA. Every course carries credit units (CU) representing its workload — a 3-unit course has three times the GPA impact of a 1-unit course.

Federal, state, and private — what stays the same

Whether you study at a federal university like Ibadan, a state university like LASU, or a private university like Covenant, the CGPA formula doesn't change — it's always quality points (grade × units) divided by total units. The classification thresholds (First Class at 4.50, etc.) are also standardised nationwide by the NUC and apply identically across all three categories.

What can differ is the percentage mark required for each letter grade at a small number of private universities, and practical factors like tuition cost, academic calendar stability, and campus facilities. For CGPA tracking purposes, the calculation itself works the same way no matter which type of university you attend.

Common questions

• What is the grading scale used in Nigerian universities?
  Nigerian universities accredited by the National Universities Commission (NUC) use a standardised 5-point CGPA scale. The grades and grade points are: A = 5.0 (70-100%), B = 4.0 (60-69%), C = 3.0 (50-59%), D = 2.0 (45-49%), E = 1.0 (40-44%), F = 0.0 (below 40%, Fail). The minimum passing grade is E (40%). This 5-point scale was reinstated by the NUC after a brief period (2017-2018) when some universities trialled a 4-point system — today the 5-point scale is the standard across federal, state, and most private universities.
• What CGPA is needed for First Class in Nigeria?
  A cumulative GPA (CGPA) of 4.50 or above on the 5-point scale earns First Class Honours. Second Class Upper Division (2:1) requires 3.50-4.49, Second Class Lower Division (2:2) requires 2.40-3.49, Third Class requires 1.50-2.39, and Pass is awarded for 1.00-1.49. First Class is highly competitive — across most Nigerian programmes, fewer than 5% of graduates achieve it, since a 4.50 CGPA requires predominantly A grades across the entire degree, particularly in the final two years which often carry more weight.
• How do I choose my university in this calculator, and what does it change?
  Use the university selector to pick from major federal, state, and private Nigerian universities. Selecting your university applies the correct marks-to-grade boundary — most universities use the NUC standard (A from 70%), but some private universities like Babcock set a higher A threshold (80%). The classification thresholds (First Class at 4.50, etc.) are standardised nationwide by the NUC and apply the same way regardless of which university you select. If your specific university's exact boundary isn't independently verified, the calculator clearly flags this and uses the NUC standard as a reasonable estimate — letter grade input always works accurately regardless of university.
• How is CGPA calculated in Nigerian universities?
  CGPA = Sum of (Grade Points × Credit Units) ÷ Total Credit Units. Example: a student takes four courses — Mathematics (3 units, grade A = 5.0), Physics (3 units, grade B = 4.0), Chemistry (2 units, grade A = 5.0), and English (2 units, grade C = 3.0). Quality points = (5.0×3) + (4.0×3) + (5.0×2) + (3.0×2) = 15 + 12 + 10 + 6 = 43. Total units = 10. GPA = 43 ÷ 10 = 4.30 — Second Class Upper. CGPA uses the same formula but sums quality points and credit units across every semester of the entire programme, not just one semester.
• Do all Nigerian universities use the same grading scale?
  Most NUC-accredited universities follow the standard 5-point scale with A starting at 70%, ensuring that a First Class from University of Lagos and a First Class from Ahmadu Bello University both mean a CGPA of 4.50 or above. However, some private universities set a higher bar for an A grade — Babcock University and Adeleke University, for example, require 80% rather than 70% for an A. The grade point VALUES (A=5, B=4, etc.) stay standardised; what differs is the percentage mark needed to earn each letter grade. Always confirm your specific university's mark boundaries with your faculty handbook.
• What is the difference between federal, state, and private universities in Nigeria?
  Federal universities are funded and administered by the Federal Government, generally have the lowest tuition fees, and include Nigeria's oldest and largest institutions like University of Ibadan and University of Lagos. State universities are funded by individual state governments, often prioritise admission for indigenes of that state, and include institutions like Lagos State University and Rivers State University. Private universities charge significantly higher tuition but often offer more stable academic calendars (avoiding the ASUU strikes that have periodically affected public universities), smaller class sizes, and modern facilities — examples include Covenant University, Babcock University, and ABUAD. The CGPA calculation formula is identical across all three categories; what can differ is the specific mark-to-grade boundary at some private institutions.
• What happens if I fail a course in a Nigerian university?
  A grade of F (0.0, below 40%) is a fail. Students must typically resit the examination or repeat (re-register for) the course, depending on whether it is a compulsory or elective course. Carryover courses — failed courses that must be retaken — can delay graduation if they clash with a later semester's timetable. The grade ultimately recorded for CGPA purposes depends on university policy: some use the better of the two attempts, others record both attempts. An E grade (1.0, 40-44%) is a low pass that satisfies the minimum requirement but drags down CGPA significantly if repeated across multiple courses.
• How many credit units are typical in a Nigerian degree programme?
  Most Nigerian undergraduate programmes require between 120 and 180 total credit units to graduate, depending on the field of study and programme duration. Programme duration ranges from 4 years (most Social Sciences, Arts, Management courses) to 5-6 years (Medicine, Pharmacy, Law, Engineering). The NUC's Benchmark Minimum Academic Standards (BMAS) documents specify exact minimum credit units per programme. A typical semester carries 15-24 credit units, strictly enforced by most universities to ensure adequate study time per course.
• Can I still get First Class if I had a weak first year?
  It depends on how weak and how many credits remain. CGPA is a credit-weighted average across all semesters of your programme. If your first two semesters totalled 36 units at a 3.0 GPA, you have 36 × 3.0 = 108 quality points. To finish with First Class (CGPA 4.50) over a 150-unit degree, your remaining 114 units must average (4.50 × 150 − 108) ÷ 114 ≈ 4.97 — nearly a perfect 5.0 across every remaining course. A weak start makes First Class mathematically very difficult, though Second Class Upper often remains achievable. Use the Goal Calculator tab to find exactly what CGPA you need going forward.
• How does Nigeria's 5-point CGPA compare to a US 4.0 GPA?
  The scales are different (5.0 maximum vs 4.0 maximum), so direct comparison requires a conversion. A common approximate mapping used by credential evaluators like World Education Services (WES): Nigerian First Class (4.50-5.00) is broadly comparable to a US GPA near 3.7-4.0. Nigerian Second Class Upper (3.50-4.49) often converts to a WES-equivalent US GPA in the 2.8-3.7 range, though the exact conversion depends on the specific CGPA value and evaluator methodology. If you are applying to graduate programmes or jobs abroad, request an official WES or equivalent credential evaluation rather than relying on an approximate conversion, since admissions committees expect a verified report.
• What is the minimum CGPA to graduate in Nigeria?
  Most Nigerian universities require a minimum cumulative CGPA of 1.00 to graduate, corresponding to the Pass classification (1.00-1.49). However, the NUC has increasingly advised universities to phase out degrees below Third Class (1.50), and in practice many modern Nigerian universities will not allow a student to graduate with a final CGPA below 1.50. Students who fall below the minimum threshold may be placed on academic probation, required to repeat courses or years, or in serious cases withdrawn from the programme. Requirements vary by university and faculty — confirm with your department.
• Is the Nigerian grading system different for polytechnics?
  Yes. Polytechnics in Nigeria award the National Diploma (ND) and Higher National Diploma (HND) rather than Bachelor's degrees, and use a completely different 4.0-scale grading system under National Board for Technical Education (NBTE) guidelines, with classifications like Distinction, Upper Credit, Lower Credit, and Pass rather than First Class or Second Class terminology. This calculator is built for the university 5-point CGPA system; polytechnic students should use their institution's specific ND/HND grading guide instead. Note also that an ND with Upper Credit makes Direct Entry into 200-level university programmes significantly easier than an ND with Lower Credit.
• Why do I need my CGPA for NYSC, and how is it shown on my transcript?
  The National Youth Service Corps (NYSC) call-up process requires submission of an official transcript showing your degree classification and final CGPA as part of mobilisation documentation. Official transcripts are issued by your university's Registrar's office and include your name, matriculation number, faculty, department, programme, every course taken with marks and grade points, semester and annual CGPA, final CGPA, and class of degree — sealed with the university stamp and signed by the Registrar or a designated officer. Request your transcript early, as processing can take several weeks at some institutions.
