Every year, millions of students write the JAMB exam hoping to enter the university. While a high JAMB score is a great start, it does not guarantee your admission.
Most universities in Nigeria do not just look at your UTME result. They use an aggregate score to pick the best students. This final score mixes your JAMB result with your O’Level grades and your Post-UTME score. If you do not know how to calculate this, you will not know your true chances of getting admitted.
Why Your Aggregate Score Matters
Universities have limited space. If thousands of people apply to study Nursing, the school needs a fair way to choose. They do this by setting a departmental cut-off mark.
Your aggregate score must meet or beat this cut-off mark. This is why a student with 280 in JAMB might lose their admission if they have poor WAEC grades. At the same time, a student with 240 in JAMB might gain admission because they scored A’s in their O’Level subjects and passed the Post-UTME heavily.
The final aggregate percentage is what the admission board actually looks at.
How Different Universities Grade Students
You cannot use one math formula for all schools. Federal and state universities have their own specific rules. Here are the three main ways schools calculate marks:
The 50:50 Method (UI, UNILORIN, FUTO) These schools keep it simple. They divide your JAMB score by 8 to get a number out of 50. Then, they divide your Post-UTME score by 2 to get another number out of 50. They add both numbers together to get your final score over 100.
The Mixed Point System (UNILAG) The University of Lagos looks at everything. They take 50% from your JAMB score and 30% from your Post-UTME. The remaining 20% comes from your 5 core O’Level subjects. For example, an A1 gives you 4 points, and a B2 gives you 3.6 points.
The No Post-UTME Method (LASU) Lagos State University does not write a Post-UTME screening exam. They take your JAMB score and turn it into a percentage. Then, they add points directly from your WAEC or NECO results. Their O’Level grading is much higher; an A1 is worth 8 points instead of 4.

Frequently Asked Questions
Do all universities use the same aggregate formula?
No, they do not. Federal and state universities have their own specific rules. For example, UI only adds your JAMB and Post-UTME scores together. UNILAG adds your JAMB, Post-UTME, and O'Level grades. Always check what method your target school uses before you calculate.
What is a good aggregate score for admission?
A good score depends entirely on the course you want to study. Highly competitive courses like Medicine, Nursing, and Law usually require a final score above 75% or 80%. Other courses might only need a 50% or 60%. You should search for your department's past cut-off marks to know your exact target.
Does this calculator save my JAMB and O'Level results?
No, your exam scores are completely private. This tool works directly in your phone or computer browser. We do not store your JAMB scores, WAEC grades, or any personal details on our website.
