AdminMany candidates scan admission notices and see the words aggregate score, then wonder how it is worked out and why it matters. The aggregate is often the number that finally decides who gets a place, especially in competitive courses. Two candidates may have the same UTME score, yet one is admitted while the other is not, because the aggregate also includes other factors such as O-level grades and screening results.
This guide explains what the post-UTME aggregate score is, the usual components, how a typical calculation works with clear examples, how to find your school’s formula, how to improve your aggregate, and the mistakes that cost candidates a place. It also links to other guides on this site that will help you prepare.
Important: There is no single national formula. Each institution publishes its own method, and policies on post-UTME screening have changed over time. The examples in this article are only illustrations to show you how the thinking works. Always use the formula published by your own school for your admission year.
What Is an Aggregate Score?
An aggregate score is a combined score that a school uses to rank candidates for admission. Instead of relying on one number, the school adds up points from several parts of your application. The candidates with the highest aggregates for a course, within the available places and quotas, are the ones considered for admission.
The Usual Components of an Aggregate
- UTME score. Your JAMB score, usually converted to a share of the total aggregate.
- O-level results. Points are given for your grades in the relevant subjects, often your best results in the core subjects for your course.
- Post-UTME or screening score. If the school holds a test or a screening exercise, your performance there adds to the total.
- Other criteria. Some schools consider additional factors, such as catchment area, special categories or other published requirements.
Not every school uses all of these. Some use only UTME and O-level results, while others add a test, and some use different weights for different courses.
A Simple Example: UTME Plus Post-UTME
Here is a purely illustrative formula. Suppose a school gives 50 marks to the UTME and 50 marks to its own screening test.
- UTME score: 280 out of 400
- Convert UTME to 50 marks: 280 divided by 8 equals 35
- Screening test score: 32 out of 50 (or converted to 50)
- Aggregate: 35 plus 32 equals 67 out of 100
Notice how the same UTME score could produce different aggregates depending on the screening score. A candidate with a lower UTME but a very good screening result might catch up.
A Second Example: UTME Plus O-Level
Now consider a school that gives 50 marks to the UTME and 50 marks to O-level performance, with no separate test.
- UTME score: 260 out of 400
- Convert UTME to 50 marks: 260 divided by 8 equals 32.5
- O-level points: the school awards points for grades, for example more points for A1 and B2 than for C4 or C5, and adds them up for the best subjects
- Suppose the O-level section gives you 38 out of 50
- Aggregate: 32.5 plus 38 equals 70.5 out of 100
In this model, strong O-level grades can raise your ranking even when your UTME score is only average.
A Third Example: Three-Part Aggregate
Some schools combine all three parts, for instance giving 40 marks to the UTME, 30 marks to O-level performance and 30 marks to screening, for a total of 100.
- UTME: 270 out of 400, converted to 40 marks: 270 divided by 10 equals 27
- O-level: 24 out of 30, based on the schoolu2019s grade points
- Screening: 25 out of 30
- Aggregate: 27 plus 24 plus 25 equals 76 out of 100
The point of this example is that you must apply each weight carefully and check your arithmetic. A small slip in conversion can lead to a wrong expectation.
How to Convert Your UTME Score Step by Step
- Find the school’s weight for UTME. For example, 50 percent, 40 percent or 30 percent of the aggregate.
- Divide your UTME score by 400 to get a fraction of the total.
- Multiply by the weight. If the UTME carries 50 marks, multiply the fraction by 50. This is the same as dividing your score by 8.
- Round only at the end, using the school’s rounding rule if one is published.
For instance, with a UTME score of 300 and a weight of 50 marks, the calculation is 300 divided by 400 equals 0.75, then 0.75 multiplied by 50 equals 37.5.
How O-Level Points Are Usually Awarded
Schools often assign points to each grade and total them for the best required subjects. A typical approach gives the highest points for A1, a slightly lower number for B2 and B3, and a lower number for credit grades C4 to C6. The exact points differ between schools, so do not assume. Some also count only one sitting, while others allow a combination of results, so check the rules before you submit your details.
When you enter your O-level information, make sure that the exam type, year, exam number and grades are correct. Errors can lead to a lower score or to disqualification.
How to Find Your School’s Formula
- Visit the official website of your school and look at the admissions or post-UTME page.
- Read the latest admission announcement, brochure or screening guidelines.
- Look for sentences that describe how scores are combined, such as the share of UTME, O-level and screening.
- Check the previous year’s notice if the new one is not yet published, but treat it as a guide only.
- Contact the admissions office through the official email or phone number if the explanation is unclear.
Avoid blogs that guess the formula without a source. A wrong assumption can lead to bad decisions.
How to Estimate Your Chances
- Calculate your own aggregate using the school’s formula and your own scores.
- Find the previous year’s aggregate cut-off for your course, if the school publishes it.
- Compare your estimate with that cut-off, remembering that the figure can move up or down.
- Think about the number of available places and the level of competition.
- Prepare a backup course and school with a lower cut-off.
An estimate is not a guarantee, but it helps you decide where to put your effort and whether to consider a change of course or institution. Our guide on changing your course and institution after the UTME explains that process.
How to Improve Your Aggregate
If you have not yet written the UTME
Focus on your UTME preparation, because it usually carries the largest weight. Use timed mock tests to build speed, and study the official syllabus carefully. See our guide on choosing and using a JAMB CBT practice app.
If you are waiting for screening
Prepare seriously for the screening exercise, if there is one. Revise your UTME subjects, practise with past-style questions and learn the format. Our guide on post-UTME requirements and how to prepare will help.
If your O-level results are a concern
Check which grades the school counts and whether a resit could help in a future cycle. Make sure you submit the right result and that your details are accurate.
For everyone
Submit complete, accurate documents on time, avoid errors in forms and respect every deadline.
Common Mistakes When Calculating or Using Aggregates
- Using the wrong formula. Do not copy another school’s method.
- Forgetting to convert the UTME score. Adding a raw score of 280 to a screening mark out of 50 gives a meaningless total.
- Counting the wrong O-level subjects. Schools often count only specific subjects.
- Ignoring quotas and catchment rules. A high aggregate does not override every other rule.
- Missing deadlines. Even a perfect aggregate cannot help if your documents are not submitted.
- Believing promises from agents. No one can legitimately add marks to your aggregate for a fee.
What If Your School Has No Post-UTME?
If your school has dropped the screening test, admission may rely mainly on your UTME score and O-level results, or on another published method. In that case, the principle is the same: the school combines the available scores into a ranking. Read the official notice carefully to see how it works. After admission is offered, follow the steps in our guide on how to accept or reject admission on JAMB CAPS.
Frequently Asked Questions
What is the post-UTME aggregate?
It is a combined score, usually made from your UTME score, O-level results and, where applicable, your screening score, used to rank candidates.
Is the aggregate formula the same in all schools?
No. Each school publishes its own formula, and it can change from year to year.
How do I convert my UTME score to a percentage?
Divide your score by 400 and multiply by 100. For the school’s weight, multiply the fraction by the weight given in the formula.
Do O-level results count in the aggregate?
In many schools, yes. Some use them as the main second component, while others use them only as an entry requirement.
Can I be admitted with a low aggregate?
It depends on the course, the available places and the competition. Compare your aggregate with the previous cut-off, and keep a backup option.
Where can I find the previous aggregate cut-off?
Check your school’s official website, admission lists and notices. Be careful with unofficial blogs.
Final Thoughts
Your aggregate score is the number that links your efforts across the UTME, your O-level results and any screening. Find your school’s official formula, convert your UTME score correctly, estimate your aggregate and compare it with recent cut-offs. Then prepare well, submit accurate documents on time and keep a realistic backup plan. With a clear understanding of how the numbers work, you can make smarter decisions and put your effort where it matters most.
