Each table comes from a document we opened on 4 November 2026, and is built from the same record the tools use. Every table here was checked against its document.
NUC CCMAS 5-point scale
From NUC's Core Curriculum and Minimum Academic Standards (CCMAS) for Computing, 2023, Tables 1.2 to 1.4, pages 20-22. Status: confirmed on 4 November 2026, for the Computing document. The CCMAS documents of other disciplines were not checked.
| 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 | 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 CGPA must be "calculated and expressed correctly to two decimal places". Under CCMAS, a CGPA below 1.00 at the end of a year means one session on probation. A student still below 1.00 after it is withdrawn.
UNN 5-point scale with no E
From the University of Nigeria, Nsukka's Faculty of Business Administration page for Accountancy. Status: confirmed on 4 November 2026. It is a department page, not a UNN-wide regulation.
| Score out of 100 | Grade | Grade point |
|---|---|---|
| 70 and above | A | 5 |
| 60 to 69 | B | 4 |
| 50 to 59 | C | 3 |
| 45 to 49 | D | 2 |
| Below 45 | F | 0 |
| Class | 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 |
| Fail | Below 1.50 |
There is no E grade, so any score below 45 is an F. The page says no Pass degree is awarded, and every attempt at a course counts.
University of Ibadan 4-point scale
From UI's notice on its newly approved grading system and its Faculty of Social Sciences page, for students admitted from the 2016/2017 session on. Status: confirmed on 4 November 2026.
| Score out of 100 | Grade | Grade point |
|---|---|---|
| 70 and above | A | 4 |
| 60 to 69 | B | 3 |
| 50 to 59 | C | 2 |
| 45 to 49 | D | 1 |
| 0 to 44 | E | 0 |
| Class | CGPA |
|---|---|
| First Class | 3.50 to 4.00 |
| Second Class Upper (2:1) | 3.00 to 3.49 |
| Second Class Lower (2:2) | 2.00 to 2.99 |
| Third Class | 1.00 to 1.99 |
| Fail | Below 1.00 |
The notice lists E as 40 to 44, worth 0, and no band below 40. The Faculty of Social Sciences page gives E as 0 to 44 and a pass mark of 45%. No degree is awarded below a CGPA of 1.00.
