Enter your CGPA, the units you have taken and the units you have left. The page shows each class of degree, the average grade point you need over the remaining units to reach it, and which classes are already safe or out of reach. It uses the NUC 5-point scale.
Enter your CGPA and your units

Your answer
Your answer shows up here once you fill in the three boxes.
What to enter
- Your CGPA now
- The CGPA on your latest result slip, on the 5-point scale.
- Units you have taken so far
- The total units (TNU) behind that CGPA.
- Units you still have to take
- Every unit left until you graduate, including carryovers you still have to clear. Use units, not semesters, because unit loads change from semester to semester.
Worked examples
A student close to First Class
A student has a CGPA of 4.30 after 90 units and has 60 units left. Which class can they still reach?
- Add the units you have and the units left: 90 + 60 = 150.
- Work out the quality points you need for a class: the class CGPA × 150, minus the points you already have (4.30 × 90 = 387.00).
- Divide by the units left (60) to get the average grade point you need from here.
- If the average is above 5.00, the class cannot be reached, because that is the highest grade point.
The best class still open is First Class. Straight As would take them to 4.58. Reaching First Class needs an average of 4.80 over the 60 units that are left, so it takes mostly As. Second Class Upper needs only 2.30.
A student near the end
A student has a CGPA of 3.00 after 100 units and has 20 units left.
- Add the units you have and the units left: 100 + 20 = 120.
- Work out the quality points you need for a class: the class CGPA × 120, minus the points you already have (3.00 × 100 = 300.00).
- Divide by the units left (20) to get the average grade point you need from here.
- If the average is above 5.00, the class cannot be reached, because that is the highest grade point.
With few units left, the best they can finish on is 3.33, so Second Class Lower is the best class still open. Second Class Upper needs more than the top grade can give, so it is out of reach.
The classes and their CGPA bands
| Class | CGPA |
|---|---|
| First Class | 4.50 to 5.00 |
| Second Class Upper | 3.50 to 4.49 |
| Second Class Lower | 2.40 to 3.49 |
| Third Class | 1.50 to 2.39 |
| Pass | 1.00 to 1.49 |
Why the units left matter more than the semesters left
The same average grade moves your CGPA more when many units are left, and less when few are. A student with 30 units left can change a CGPA far more than one with 6 units left. That is why this page asks for units, and why a plain count of semesters would mislead you.
How it is calculated
- Add the units you have taken and the units left to get the total units at the end.
- Multiply the CGPA a class starts at by the total units at the end. This is the credit points you need in total.
- Take away the credit points you already have, which is your CGPA times your units so far.
- Divide what is left by the units remaining. That is the average grade point you need from here.
- If the answer is above 5, the class cannot be reached, because 5 is the highest grade point.
Average needed = (class CGPA × total units at the end – CGPA now × units so far) ÷ units left
Assumptions to keep in mind
- The class bands are the NUC bands. Your school may apply its own rules for the final CGPA, such as weighting the final year, so check your handbook.
- The answer is an average over all the units left. You can reach it with a mix of grades, as long as the average works out.
- A class is shown as already secured only if even failing every remaining unit would still leave you in it. That is a rare case.
- The page assumes you pass every unit you take. Carryovers and retakes change the units left. Use the carryover calculator to see their effect.
- The CGPA is rounded to two decimals before the class is read, as most schools do. Some schools truncate instead.
Mistakes that give the wrong answer
Counting semesters instead of units
A semester of 15 units and a semester of 24 units do not move your CGPA by the same amount. Use units.
Leaving out your carryovers
If you still have a failed course to retake, its units are part of the units you have left.
Reading the average as a grade for every course
The needed average is across all your remaining units. Strong grades in big courses can make up for weaker ones in small courses.
Using a CGPA from the wrong scale
This page uses the university 5-point scale. For a polytechnic, use the polytechnic CGPA calculator.
Questions students ask
How do I work out the CGPA I need for First Class?
Multiply 4.50 by your total units at the end, take away the credit points you already have, and divide by the units left. If the answer is above 5.00, First Class is out of reach. The calculator does it for every class at once.
Can I still make a Second Class Upper?
Enter your CGPA and units. The table shows whether Second Class Upper is possible, and the average you need for it. If it says Not possible, even straight As over your remaining units would fall short.
What CGPA do I need for each class in Nigeria?
On the NUC scale, First Class is 4.50 to 5.00, Second Class Upper is 3.50 to 4.49, Second Class Lower is 2.40 to 3.49, Third Class is 1.50 to 2.39, and a Pass is 1.00 to 1.49.
Does it matter how many units I have left?
Yes. The fewer units left, the less one good semester can change your CGPA. The page shows the best CGPA you can still finish on.
How do I find my CGPA and total units?
They are on your latest result slip, often as CGPA and TNU. If you do not have them, use the Nigerian CGPA calculator to work them out from your courses.
