How to calculate your JAMB aggregate score

If you want to get admission into any Nigerian higher institution, simply passing your JAMB UTME (Unified Tertiary Matriculation Examination) is not enough anymore.

Most schools calculate your aggregate score based on your JAMB score, Post UTME score, and sometimes your O’Level grades.

So, JAMB alone will not help you get admission. If you want to be in a better position to get admission, you need to score high in post-UTME and JAMB.

A high aggregate score is what you need to get admission (and it will only come from you scoring high in JAMB as well as in post-UTME or O’leve results).

To know your aggregate score, you can calculate it using different methods. which we will show you here.

However, you will learn more than that here, we will also show you:

• The formula used for calculating the aggregate score
• How different universities calculate aggregate scores
• Examples of JAMB aggregate score calculations
• FAQs about university admission cut-off marks.

What is a JAMB aggregate score?

Your JAMB aggregate score is a combination of your:

• JAMB UTME score (out of 400)
• Post UTME score (if applicable, out of 100)
• O’Level (WAEC, NECO, or NABTEB) grades (some universities include this)

Each school has its method of weighing these scores and they will use the outcome to know if you are eligible for admission.

In many schools, they combine your JAMB score and post-UTME score. The standard calculation formula they use is:

In some schools, they will replace the Post-UTME score with O’Level grading (WAEC/NECO) or use a different weighting system.

How to calculate JAMB aggregate score

To calculate your JAMB aggregate score, you use both your JAMB (UTME) score and your post-UTME or O’Level grades, depending on your chosen school’s admission policy.

Most universities use a 50:50, 60:40, or 70:30 weighting system between JAMB and Post-UTME/O’Level results.

In a normal 50:50 system, your JAMB score (out of 400) is divided by 8 to get a score over 50, while your Post-UTME score (out of 100) is divided by 2 to get another 50, and then both are added together.

If a school uses O’Level grades, they assign points to A1, B2, B3, C4, C5, and C6, sum them up, and adjust based on a percentage system.

Some schools use a 60:40 ratio, where your JAMB score is divided by 4 (to get a score out of 60) and your Post-UTME score is divided by 2.5 (to get a score out of 40).

Don’t get confused, here is how you can do it by yourself to know your exact score.

Method 1: How to calculate JAMB aggregate score in a 50:50 system where JAMB contributes 50% and post-UTME contributes 50%

As we said above, there are different systems. The one we want to talk about now is the 50:50 system (which most schools use).

This system considers only your JAMB and post-UTME scores, schools that use this system don’t use your O’level results to judge you.

If your chosen school uses this system, it means you should only worry about your post-UTME and JAMB score because they won’t include your O’level results in calculating your aggregate score.

To calculate your JAMB aggregate score in a 50:50 system, use the formula below:

Step 1: We will convert your JAMB score to aggregate points

To start, we need to change your JAMB score to aggregate points.

See how to do it below:

That means, if your JAMB score is 280, you divide it by 8 and you will get 35 aggregate points.

Therefore, for JAMB, your aggregate point is 35.

Step 2: We have to convert your post-UTME score to aggregate points as well

If you noticed, Post-UTME scores are usually graded over 100 but converted to a scale of 50 for aggregate calculations.

To do this, divide your post-UTME score by 2.

From the formula above, if you score 70 in post-UTME, your aggregate will be 70 divided by 2, which is 35.

If you scored 60 in post-UTME, it will be 60 divided by 2, which is 30.

Step 3: We will then add your JAMB and post-UTME points to get the total aggregate score

Now, add the JAMB points and the Post-UTME points together.

Example 1: For a candidate with a JAMB score of 280 and a Post-UTME score of 70

JAMB point which is 35 + post-UTME point which is 35 = 70 aggregate score.

Final Aggregate Score = 70

Example 2: For a candidate with a JAMB score of 240 and a Post-UTME score of 60

JAMB point which is 30 + post-UTME point which is 30= 60 aggregate score.

Final Aggregate Score = 60

Method 2: How to calculate your JAMB aggregate score using the O’Level grading method: JAMB + O’Level results

Schools like the University of Lagos (UNILAG), use this system sometimes (not all the time).

They get the aggregate score by judging every student’s JAMB score and O’Level results instead of post-UTME.

In this system, there is no post-UTME. Below is how the aggregate score is calculated using only JAMB and O’level results.

Each O’Level subject is assigned a score based on the grade:

If your school uses this method, they will sum up your best five subjects (relevant to your course) and add the score to your JAMB points.

The good thing about this method is that they only pick subjects that are important to your course.

To calculate using this method, divide your JAMB score by 8 and sum the points for each of your five O’Level subjects.

Then, add the total together, see the example below:

Assuming your JAMB score is 280:

With a 61 aggregate score, you will qualify for many top-rated courses.

Method 3: How to calculate your JAMB aggregate score using your JAMB score (50%) + Post UTME score (30%) + O’Level results (20%)

Some universities, like OAU and UI, combine your O’Level results, JAMB score and post-UTME score into their calculation:

To use this method in checking your aggregate JAMB score, you should:

• Divide your JAMB score by 8
• Divide your Post UTME score by 2
• Grade your O’Level using A1 = 6 points, B2 = 5 points, etc.
• Sum up all scores.

For example:

• If your JAMB score is: 300
• Your post UTME score: 80
• And, your O’Level (5 relevant subjects): A1, B2, B2, B3, C4

You will have:

• JAMB Contribution: 300 ÷ 8 = 37.5
• Post UTME Contribution: 80 ÷ 2 = 40
• O’Level Contribution: (6+5+5+4+3) = 23

Your aggregate score is = 37.5 + 40 + 23 = 100.5

Method 4: How to calculate your JAMB aggregate score using the 60:40 ratio system where your JAMB score is (60%) and Post UTME score is (40%)

This method considers only your JAMB and post-UTME scores but the difference is that your JAMB contributes 60% of the entire aggregate while post-UTME contributes the remaining 40%.

Remember, the one we discussed before, JAMB contributed 50% and post-UMTE contributed 50%.

To calculate the aggregate score using this 60:40 ratio method, you should:

Step 1: Divide your JAMB score by 4

Since JAMB contributes 60% to the aggregate score, you will divide your JAMB score by 4.

​

Step 2: Divide your post-UTME score by 2.5

Since it contributes 40% to the aggregate score, divide your post-UTME score by 2.5.

​

Step 3: Then add both contributions together

Finally, sum up both values to get your total aggregate score.

For example

Suppose a student has:

• JAMB Score: 280
• Post-UTME Score: 75

Step 1: JAMB Contribution

280÷4 ​= 70

Step 2: Post-UTME Contribution

75÷2.5 = 30​

Step 3: Aggregate Score

70+30 = 100

Thus, the student’s aggregate score is 100.

Another important thing you should note is that some schools can decide to replace the 40% from post-UTME with O’level results.

In that case, instead of post-UTME bearing the 40%, it will be your O’level results that will give you the score for the 40%.

With this, the formula will now be:

When JAMB (60%) and O’Level (40%)

To calculate this:

• Divide your JAMB score by 4
• Use your O’Level grading scale (e.g., A1 = 10 points, B2 = 9 points, etc.)
• Add both scores together

Example of this calculation:

• If your JAMB score is: 250
• And, your O’Level result is: A1, B2, B3, B3, C4

With this, your:

• JAMB contribution will be: 250 ÷ 4 = 62.5
• And, your O’Level contribution will be: (10+9+8+8+6) = 41

The aggregate score will be 62.5 + 41 = 103.5

You can use any of the five methods we discussed here to calculate your JAMB aggregate score.

Another important thing you need to keep in mind is your school’s cut-off mark for the particular course you applied for.

Check your school’s cut-off mark

Each course has a different cut-off mark based on competition and demand.

If you want to get admission into any top-rated course, you need to have higher aggregate scores than others.

Example of aggregate score cut-off marks for some courses

If you get an aggregate score of 61, you will qualify for Accounting but will likely not be admitted for Medicine.

Frequently Asked Questions (FAQs)

How do I know my university’s calculation method?

To know the method your school will use, check their admission guidelines or the school website.

You can also call the school admission unit if they have contact information.

Each school has its system. Check your university’s admission guidelines or visit the school’s website for details.

Can I gain admission with only my JAMB score?

You can get admission with only JAMB if you want a school like NOUN or some private schools that do not require Post UTME or O’level results.

If you want to increase your chances of getting admission, you need more than a high JAMB score, your pos-UTME score is also important.
