Source: NUC, Computing CCMAS 2023 FINAL (Tables 1.2 to 1.4, pp. 20-22), opened 4 November 2026.
NUC CCMAS counts every course, passed or failed, and every attempt. Enter a course you take again as a new course in the semester you take it.
CGPA so far
For semesters you do not enter above: the CGPA and total units from your last result. A CGPA printed to 2 decimals can move the result in the last decimal.
Scale in use: NUC CCMAS 5-point scale (A to F)
| Score out of 100 | Grade | Grade point |
|---|---|---|
| 70 to 100 | A | 5 |
| 60 to 69 | B | 4 |
| 50 to 59 | C | 3 |
| 45 to 49 | D | 2 |
| 40 to 44 | E | 1 |
| 0 to 39 | F | 0 |
| Class of degree | CGPA |
|---|---|
| First Class | 4.50 to 5.00 |
| Second Class Upper (2:1) | 3.50 to 4.49 |
| Second Class Lower (2:2) | 2.40 to 3.49 |
| Third Class | 1.50 to 2.39 |
| Pass | 1.00 to 1.49 |
| No class of degree | Below 1.00 |
The class of degree comes from your final CGPA. The bands are printed to 2 decimals, so the CGPA goes to 2 decimals first.
Notes on this scale
CCMAS asks for the CGPA to 2 decimals and does not say whether to round or cut off. The calculator rounds half up, shows the exact value under Before rounding, and says when cutting off would give another class.
The CCMAS read is the one for Computing. The documents of other disciplines were not checked.
Not covered yet. UNILAG, NOUN, UNILORIN, OAU, ABU and other universities: their own grading rules were not read, so there is no preset for them. The CCMAS documents of disciplines other than Computing: only the Computing one was read. Polytechnic CGPA (NBTE): its grade weightings and classes are confirmed, but neither NBTE curriculum read says how the CGPA is averaged. CGPA to percentage, and 5-point to 4-point conversions: no NUC or university formula was found, so GradeCat gives none.
This is an estimate, not an official result. Your university's result slip or transcript decides.

How to calculate CGPA in Nigeria
Multiply each course's units by its grade point. Add these up, then divide by the total units.
CGPA = Σ(units × grade point) ÷ Σ units
A semester's GPA is the same sum over that semester's courses. NUC's Core Curriculum and Minimum Academic Standards (CCMAS) for Computing, 2023, Tables 1.2 to 1.4, divides by the units of every course taken, whether passed or failed, and counts every attempt.
Your CGPA is not the average of your semester GPAs. Made-up example: a CGPA so far of 3.45 over 60 units is 207 points. A new semester of 34 points over 11 units makes (207 + 34) ÷ 71 = 3.39, not the 3.27 you get by averaging 3.45 and 3.09.
Grade points on each scale
The same score can earn a different grade point at a different university. The CCMAS has an E for 40 to 44. UNN's Faculty of Business Administration page has no E: anything below 45 is an F. The University of Ibadan's 4-point scale applies to students admitted from 2016/2017.
| Score out of 100 | NUC CCMAS | UNN | UI |
|---|---|---|---|
| 70 to 100 | A, 5 | A, 5 | A, 4 |
| 60 to 69 | B, 4 | B, 4 | B, 3 |
| 50 to 59 | C, 3 | C, 3 | C, 2 |
| 45 to 49 | D, 2 | D, 2 | D, 1 |
| 40 to 44 | E, 1 | F, 0 | E, 0 |
| 0 to 39 | F, 0 | F, 0 | E, 0 |
UI's news page lists E as 40 to 44, worth 0, and no band below 40. UI's Faculty of Social Sciences page gives E as 0 to 44, with a pass mark of 45%. Both give 0 points below 45. Every table, with its source and status, is on the grading scale and class of degree page.
Class of degree
The class of degree comes from your final CGPA, which the CCMAS says must be "calculated and expressed correctly to two decimal places".
| Class of degree | NUC CCMAS | UNN | UI |
|---|---|---|---|
| First Class | 4.50 to 5.00 | 4.50 to 5.00 | 3.50 to 4.00 |
| Second Class Upper (2:1) | 3.50 to 4.49 | 3.50 to 4.49 | 3.00 to 3.49 |
| Second Class Lower (2:2) | 2.40 to 3.49 | 2.40 to 3.49 | 2.00 to 2.99 |
| Third Class | 1.50 to 2.39 | 1.50 to 2.39 | 1.00 to 1.99 |
| Pass | 1.00 to 1.49 | None | None |
| Below the lowest band | Below 1.00: no class of degree | Below 1.50: fail | Below 1.00: fail |
Under the CCMAS, a CGPA below 1.00 at the end of a year means one session on probation, and a student still below 1.00 after it is withdrawn. UNN's page awards no Pass degree. The University of Abuja's Civil Engineering page keeps the Pass class, from 1.00 to 1.49.
Worked example: one set of scores on three scales
Made-up example: five courses, 11 units.
| Course | Units | Score | NUC CCMAS | UNN | UI |
|---|---|---|---|---|---|
| Course 1 | 3 | 72 | A (5) | A (5) | A (4) |
| Course 2 | 2 | 63 | B (4) | B (4) | B (3) |
| Course 3 | 3 | 55 | C (3) | C (3) | C (2) |
| Course 4 | 2 | 42 | E (1) | F (0) | E (0) |
| Course 5 | 1 | 38 | F (0) | F (0) | E (0) |
| Total points | 11 | 34 | 32 | 24 | |
| GPA | 3.09 | 2.91 | 2.18 |
On the CCMAS scale, (15 + 8 + 9 + 2 + 0) ÷ 11 = 34 ÷ 11 = 3.09, a Second Class Lower. UNN has no E, so the 42 is an F worth 0: (15 + 8 + 9 + 0 + 0) ÷ 11 = 32 ÷ 11 = 2.91, also a Second Class Lower. On UI's 4-point scale, (12 + 6 + 6 + 0 + 0) ÷ 11 = 24 ÷ 11 = 2.18, a Second Class Lower on UI's bands.
With 46 in place of 42, that course is a D, worth 1 point at UI: (12 + 6 + 6 + 2 + 0) ÷ 11 = 26 ÷ 11 = 2.36.
Failed and repeated courses
Under the CCMAS and on UNN's page, a failed course counts. Its units go into the total with 0 grade points, so it pulls your CGPA down. A course you take again counts again, so enter the new attempt as another course in the semester you take it.
Made-up example: 15 units with 60 points is a GPA of 4.00. Add a 3-unit course with an F, and the GPA is 60 ÷ 18 = 3.33. That moves it from the Second Class Upper band to the Second Class Lower band.
Neither UI page we read says how a failed or repeated course counts, so on the UI scale the calculator counts every course you enter.
Rounding to 2 decimals
The CCMAS asks for 2 decimals but does not say whether to round or cut off. The calculator rounds half up and shows the exact value under Before rounding. When cutting off would put you in another band, it says so.
Made-up example: 679 points over 151 units is 4.4967. Rounded to 2 decimals it is 4.50, a First Class. Cut off after 2 decimals it is 4.49, a Second Class Upper. Check how your university rounds.
What this calculator does not cover yet
UNILAG, NOUN, UNILORIN, OAU, ABU and other universities: their own grading rules were not read, so there is no preset for them. The CCMAS documents of disciplines other than Computing: only the Computing one was read. Polytechnic CGPA (NBTE): its grade weightings and classes are confirmed, but neither NBTE curriculum read says how the CGPA is averaged. CGPA to percentage, and 5-point to 4-point conversions: no NUC or university formula was found, so GradeCat gives none. We add a university only after we have read its own rules.
CGPA calculator FAQ
How do I calculate my CGPA in Nigeria?
Multiply each course's units by its grade point, add these up over every semester, and divide by your total units. For 34 points over 11 units, that is 34 ÷ 11 = 3.09.
What CGPA is a First Class in Nigeria?
4.50 to 5.00 on the 5-point scale, under the CCMAS and on UNN's page. At the University of Ibadan, on its 4-point scale, a First Class is 3.50 to 4.00.
What CGPA is a 2:1?
A Second Class Upper is 3.50 to 4.49 on the 5-point scale, and 3.00 to 3.49 at UI. A 2:2, Second Class Lower, is 2.40 to 3.49 on the 5-point scale.
Does a failed course count in my CGPA?
Yes, under the CCMAS and on UNN's page. Its units go into the total with 0 grade points, and a course you take again counts again. Neither UI page we read says.
How do I calculate CGPA on a 4.0 scale?
At UI, A is 4, B 3, C 2, D 1 and E 0, and the sum is the same. 3 units of A and 2 units of B give (12 + 6) ÷ 5 = 3.60, a First Class on UI's bands.
Is there still a Pass degree in Nigeria?
It depends on the university. The CCMAS lists Pass from 1.00 to 1.49, and the University of Abuja's Civil Engineering page keeps it. UNN's page says no Pass degree is awarded, and below 1.50 is a fail.
What happens if my CGPA is below 1.00?
Under the CCMAS, a CGPA below 1.00 at the end of a year means one session on probation, and a student still below 1.00 after it is withdrawn. At UI, no degree is awarded below 1.00.
Can I convert my CGPA to a percentage?
GradeCat found no NUC or university formula for it, so this calculator gives none. Use the figure your university gives, if it gives one.
