After writing the Unified Tertiary Matriculation Examination and participating in a school’s Post-UTME screening, the next question many candidates ask is: “How can I calculate my admission aggregate score?”

Your JAMB score alone may not be the final score used to decide whether you will be admitted. Many Nigerian universities combine a candidate’s JAMB result with the Post-UTME score, O’level grades or both to produce a final admission aggregate.

This aggregate score is then compared with the cut-off mark for the candidate’s chosen course.

However, there is no single aggregate calculation formula used by every university in Nigeria. One institution may give equal weight to JAMB and Post-UTME, while another may divide the total score among JAMB, O’level grades and Post-UTME performance.

For example, the University of Lagos used an assessment structure of 50% for JAMB, 20% for O’level results and 30% for Post-UTME for its 2025/2026 admission exercise. Candidates should not assume that this formula applies to every university or that it will remain unchanged for future sessions.

This article explains how to calculate your JAMB and Post-UTME aggregate score in 2026 using the most common methods. It also provides practical examples, explains the meaning of aggregate scores and identifies common mistakes candidates should avoid.

What Is an Admission Aggregate Score?

An admission aggregate score is the final score calculated from two or more components of a candidate’s admission performance.

The components may include:

• JAMB UTME score
• Post-UTME score
• O’level grades
• Number of O’level sittings
• Screening performance
• Other requirements approved by the institution

The purpose of an aggregate score is to place the candidate’s different results on a common scale, usually from 0 to 100.

JAMB scores candidates over 400, while many Post-UTME examinations are marked over 100. Some institutions mark their Post-UTME over 30, 40 or 50.

Because these results use different maximum scores, institutions convert them into percentages or weighted points before adding them together.

For example, a university may decide that:

• JAMB contributes 50 marks.
• Post-UTME contributes 50 marks.
• The final aggregate is calculated over 100.

Another university may decide that:

• JAMB contributes 50 marks.
• O’level results contribute 20 marks.
• Post-UTME contributes 30 marks.
• The final aggregate is calculated over 100.

Your aggregate score is therefore different from your original JAMB score.

Is JAMB Score the Same as Aggregate Score?

A JAMB score is not usually the same as an admission aggregate score.

Your JAMB score is the total mark you obtained from the four subjects you answered during UTME. The highest possible UTME score is 400.

Your aggregate score is the final score produced after your institution converts and combines the admission components it uses.

For instance, suppose you scored 280 in JAMB and 70 in Post-UTME.

Your JAMB score remains 280 out of 400. However, if your institution uses a 50:50 calculation method, your final aggregate would be 70 out of 100.

Therefore:

• JAMB score: 280 out of 400
• Post-UTME score: 70 out of 100
• Admission aggregate: 70 out of 100

The aggregate score is usually the figure compared with the departmental admission cut-off mark.

Why Do Schools Calculate Aggregate Scores?

Universities calculate aggregate scores because relying on JAMB scores alone may not provide the complete information they want for admission selection.

A university may receive thousands of applications from candidates who have already met its minimum JAMB cut-off mark. The school may have only a limited number of available spaces.

The institution therefore uses additional screening information to rank candidates.

Aggregate scores help schools to:

1. Combine JAMB and screening performance.
2. Compare candidates using a common scoring scale.
3. Rank applicants for individual departments.
4. select candidates for limited admission spaces.
5. Apply merit and other approved admission considerations.
6. Determine departmental cut-off marks.
7. Reduce the number of candidates competing for a programme.

A candidate with a high JAMB score may still have a lower aggregate if the candidate performs poorly in Post-UTME.

Similarly, a candidate with a moderate JAMB score may improve the final aggregate through an excellent Post-UTME result.

Before Calculating Your Aggregate Score

Before using any calculation formula, confirm the method officially approved by your chosen institution.

Do not calculate your aggregate with a formula you found on an unrelated school website or an old social media post.

Check the following information:

• The institution’s official admission website
• The correct academic session
• The weight assigned to JAMB
• The weight assigned to Post-UTME
• Whether O’level results are included
• How O’level grades are converted
• Whether one or two sittings affect the score
• The maximum Post-UTME mark
• The final departmental cut-off mark

A formula used during the 2024/2025 admission exercise may be changed for the 2026/2027 exercise.

Candidates should always look for the latest screening instructions published by the institution.

For example, the University of Lagos announced that candidates who selected it as their first choice and scored at least 200 were eligible for its 2026/2027 Post-UTME screening. This institutional requirement was higher than the national university minimum of 150 approved for the 2026 admission exercise.

This shows why candidates must distinguish between JAMB’s general benchmark and an individual school’s admission process.

Method One: JAMB and Post-UTME Carry 50% Each

One of the most common aggregate calculation methods gives 50% to JAMB and 50% to Post-UTME.

Under this method:

• JAMB contributes a maximum of 50 marks.
• Post-UTME contributes a maximum of 50 marks.
• The total aggregate is calculated over 100.

The formula is:

Aggregate score = JAMB score divided by 8 + Post-UTME score divided by 2

This formula assumes that:

• JAMB is marked over 400.
• Post-UTME is marked over 100.
• Each result contributes 50%.

Why is the JAMB score divided by 8?

The maximum JAMB score is 400.

To convert 400 to 50:

400 ÷ 8 = 50

Therefore, dividing a candidate’s JAMB score by 8 converts it to a score over 50.

Why is Post-UTME divided by 2?

The maximum Post-UTME score in this example is 100.

To convert 100 to 50:

100 ÷ 2 = 50

Therefore, dividing the Post-UTME score by 2 converts it to a score over 50.

The two converted results are added together to obtain an aggregate over 100.

Example One: JAMB Score of 280 and Post-UTME Score of 70

Suppose a candidate obtained:

• JAMB score: 280
• Post-UTME score: 70

Step 1: Convert the JAMB score

280 ÷ 8 = 35

The candidate receives 35 marks from JAMB.

Step 2: Convert the Post-UTME score

70 ÷ 2 = 35

The candidate receives 35 marks from Post-UTME.

Step 3: Add the two results

35 + 35 = 70

The candidate’s aggregate score is 70%.

Example Two: JAMB Score of 240 and Post-UTME Score of 60

JAMB component:

240 ÷ 8 = 30

Post-UTME component:

60 ÷ 2 = 30

Aggregate:

30 + 30 = 60

The candidate’s aggregate score is 60%.

Example Three: JAMB Score of 320 and Post-UTME Score of 80

JAMB component:

320 ÷ 8 = 40

Post-UTME component:

80 ÷ 2 = 40

Aggregate:

40 + 40 = 80

The candidate’s aggregate score is 80%.

Example Four: High JAMB Score but Low Post-UTME Score

Suppose a candidate scored:

• JAMB: 320
• Post-UTME: 40

JAMB component:

320 ÷ 8 = 40

Post-UTME component:

40 ÷ 2 = 20

Aggregate:

40 + 20 = 60

The candidate’s aggregate score is 60%.

Although the candidate scored 320 in JAMB, the low Post-UTME performance reduced the final aggregate.

This demonstrates why candidates should prepare seriously for Post-UTME instead of assuming that a high JAMB score guarantees admission.

Example Five: Moderate JAMB Score but Excellent Post-UTME

Suppose another candidate scored:

• JAMB: 240
• Post-UTME: 90

JAMB component:

240 ÷ 8 = 30

Post-UTME component:

90 ÷ 2 = 45

Aggregate:

30 + 45 = 75

The candidate’s aggregate score is 75%.

The excellent Post-UTME performance significantly improved the final admission score.

However, this calculation is only valid if the institution gives equal weight to JAMB and Post-UTME.

Method Two: Add JAMB and Post-UTME, Then Divide by Two

Some institutions may present their calculation as an average of the JAMB and Post-UTME scores after placing both scores on the same scale.

Suppose the Post-UTME is also marked over 400.

The formula may be:

Aggregate score = JAMB score + Post-UTME score, divided by 2

For example:

• JAMB score: 260
• Post-UTME score: 300

Add both scores:

260 + 300 = 560

Divide by two:

560 ÷ 2 = 280

The candidate’s average is 280 out of 400.

This method should only be used when the institution has scored or converted the Post-UTME result to the same maximum mark as JAMB.

Do not use this formula when your Post-UTME result is marked over 100 unless the school specifically instructs you to do so.

Adding 280 out of 400 directly to 70 out of 100 without converting either score would produce an inaccurate result.

Method Three: JAMB 50%, O’Level 20% and Post-UTME 30%

Some institutions include O’level grades when calculating admission aggregates.

A notable example is the University of Lagos assessment structure used for the 2025/2026 UTME admission exercise:

• JAMB: 50%
• O’level: 20%
• Post-UTME: 30%

Under this type of method, the maximum aggregate score is 100.

Calculating the JAMB component

Because JAMB contributes 50 marks, divide the candidate’s JAMB score by 8.

For example, if the candidate scored 280:

280 ÷ 8 = 35

The JAMB contribution is 35 out of 50.

Calculating the O’level component

The institution assigns points to the relevant O’level grades.

The exact points must be obtained from the school’s official scoring table. Candidates should not invent a grading scale or use an unofficial table.

The institution may consider the five subjects required for the selected course.

Suppose the candidate’s five relevant O’level grades produce 16 points out of the maximum 20.

The O’level contribution is 16.

Calculating the Post-UTME component

If the Post-UTME is already marked over 30, the candidate may use the score directly.

Suppose the candidate scored 24 out of 30.

The Post-UTME contribution is 24.

Adding the components

JAMB: 35

O’level: 16

Post-UTME: 24

Aggregate:

35 + 16 + 24 = 75

The candidate’s aggregate score is 75%.

The example above is for explanation. Candidates must use the actual O’level grading table and assessment instructions published by their institution.

Converting a Post-UTME Score to 30%

Suppose a school gives Post-UTME a weight of 30%, but the examination is marked over 100.

You can calculate the Post-UTME contribution using this formula:

Candidate’s Post-UTME score divided by 100, multiplied by 30

For example, if the candidate scored 80 out of 100:

80 ÷ 100 = 0.8

0.8 × 30 = 24

The candidate receives 24 marks out of the available 30.

A faster formula is:

Post-UTME score × 0.3

Therefore:

80 × 0.3 = 24

The Post-UTME contribution is 24.

Another example

Post-UTME score: 70 out of 100

70 × 0.3 = 21

The candidate receives 21 marks out of 30.

One more example

Post-UTME score: 55 out of 100

55 × 0.3 = 16.5

The candidate receives 16.5 marks out of 30.

Converting JAMB to Different Percentages

The method used to convert your JAMB score depends on the percentage assigned by the institution.

When JAMB carries 50%

Use:

JAMB score ÷ 8

Examples:

JAMB score	Contribution out of 50
200	25
220	27.5
240	30
260	32.5
280	35
300	37.5
320	40
340	42.5
360	45
400	50

When JAMB carries 60%

Use:

JAMB score divided by 400, multiplied by 60

A shorter formula is:

JAMB score × 0.15

For example:

280 × 0.15 = 42

The candidate receives 42 out of 60.

When JAMB carries 70%

Use:

JAMB score divided by 400, multiplied by 70

A shorter formula is:

JAMB score × 0.175

For example:

280 × 0.175 = 49

The candidate receives 49 out of 70.

When JAMB carries 40%

Use:

JAMB score divided by 400, multiplied by 40

A shorter formula is:

JAMB score ÷ 10

For example:

280 ÷ 10 = 28

The candidate receives 28 out of 40.

General Formula for Converting Any Score

You can use this general formula when an institution assigns a particular percentage to an examination:

Converted score = Candidate’s score ÷ Maximum possible score × Assigned weight

Suppose you scored 65 in an examination marked over 100, and the examination carries 40% of the aggregate.

Your converted score is:

65 ÷ 100 × 40 = 26

You receive 26 marks out of 40.

Suppose you scored 300 in JAMB, and JAMB carries 60%.

Your converted score is:

300 ÷ 400 × 60 = 45

You receive 45 marks out of 60.

This general formula can be used for JAMB, Post-UTME and other admission components, provided you know:

1. Your score.
2. The maximum possible score.
3. The percentage or weight assigned by the institution.

Method Four: JAMB and O’Level Screening Without Post-UTME Examination

Not every institution conducts a written Post-UTME examination.

Some schools carry out an online admission screening using:

• JAMB score
• O’level grades
• Number of O’level sittings
• Required course subjects
• Other stated criteria

In such cases, the candidate may not have a separate Post-UTME examination score.

The institution may assign a percentage to JAMB and another percentage to O’level grades.

For example, a hypothetical institution may use:

• JAMB: 70%
• O’level results: 30%

Suppose a candidate scores 280 in JAMB.

JAMB contribution:

280 ÷ 400 × 70 = 49

Suppose the candidate obtains 24 out of the available 30 O’level points.

Aggregate:

49 + 24 = 73

The candidate’s aggregate score is 73%.

This is only an illustration. Candidates must obtain the correct O’level grading system from the institution.

How O’Level Grades May Affect Your Aggregate Score

Where an institution includes O’level results, candidates with stronger grades may receive more points.

For example, an A1 may receive more points than a B3, while a B3 may receive more points than a C6.

Some schools may also give more points to candidates who obtained all required credits in one sitting than candidates combining two sittings.

However, grading methods differ.

A school may:

• Use the five relevant subjects.
• Use only the four subjects related to the UTME combination.
• Include English Language and Mathematics.
• Award different points for A1 to C6.
• Deduct points for two sittings.
• Accept only one sitting for particular programmes.
• Exclude grades that are not relevant to the chosen course.

Candidates should not calculate O’level points using a table from another university.

For example, the University of Lagos required 2026/2027 Post-UTME applicants to possess five relevant O’level credit passes at one sitting, including English Language and Mathematics.

Requirements may be different at another institution or for a different programme.

How to Calculate Aggregate When Post-UTME Is Marked Over 30

When an institution’s Post-UTME result is already marked over 30 and Post-UTME contributes 30%, do not divide it again.

For example:

• JAMB score: 296
• O’level score: 17 out of 20
• Post-UTME score: 25 out of 30

JAMB component:

296 ÷ 8 = 37

O’level component:

17

Post-UTME component:

25

Aggregate:

37 + 17 + 25 = 79

The candidate’s aggregate score is 79%.

A common mistake would be to divide the Post-UTME score of 25 by another number. That would incorrectly reduce the candidate’s result.

Always confirm the maximum mark attached to the score shown on your result slip.

How to Calculate Aggregate When Post-UTME Is Marked Over 40

Suppose the institution assigns:

• JAMB: 60%
• Post-UTME: 40%

Assume the candidate obtained:

• JAMB score: 300
• Post-UTME score: 32 out of 40

JAMB contribution:

300 ÷ 400 × 60 = 45

Because the Post-UTME score is already over 40, use 32 directly.

Aggregate:

45 + 32 = 77

The candidate’s aggregate is 77%.

If the Post-UTME result were displayed as a percentage over 100 instead, it would need to be converted to 40%.

How to Know Whether Your Aggregate Score Is Good

There is no single aggregate score that is good for every university and course.

Whether your score is competitive depends on:

• Your chosen university
• Your selected course
• The number of applicants
• Available admission spaces
• The performance of other candidates
• The departmental cut-off mark
• Merit and other approved admission categories

An aggregate score of 60 may be sufficient for a less competitive programme in one institution but too low for Nursing, Medicine, Law or Pharmacy in the same institution.

Similarly, an aggregate of 70 may be excellent for one programme but below the final merit mark for another.

The University of Ibadan’s 2025/2026 cut-off marks, for example, varied by programme and admission category rather than using one final mark for every course.

Candidates should therefore compare their aggregates with the official departmental marks published for the correct academic session.

Aggregate Score Versus Departmental Cut-Off Mark

Your aggregate score represents your own admission performance.

The departmental cut-off mark is the minimum aggregate required for admission consideration into a particular programme.

Suppose your aggregate is 68 and the departmental merit cut-off mark is 65.

You are above the departmental mark by three points.

However, being above the cut-off mark does not always guarantee immediate admission. You must still satisfy the required subject combination, O’level credits, age requirement, first-choice condition and other institutional requirements.

Suppose your aggregate is 63 and the departmental cut-off is 65.

You are below the departmental mark by two points.

The institution may:

• Leave you without admission.
• Consider you under another approved category.
• Recommend you for another programme.
• Offer a course transfer through JAMB CAPS.
• Invite you to apply for a supplementary programme.

The outcome depends on the institution’s admission policy and available spaces.

JAMB Cut-Off Mark Versus Aggregate Score

The JAMB cut-off mark determines whether your UTME score is high enough for a category of institution or a school’s screening exercise.

Your aggregate score is calculated after the relevant admission components have been combined.

For 2026, JAMB announced minimum tolerable admission scores of:

• Universities: 150
• Colleges of nursing: 140
• Polytechnics: 100
• Monotechnics: 100
• Colleges of agriculture: 100
• Colleges of education: 100
• Innovation Enterprise Institutions: 100

These minimum scores are not aggregate scores.

A candidate who scores 150 may meet the national university benchmark but may not qualify for a university that requires 200 for Post-UTME registration.

The candidate must first meet the institution’s JAMB requirement before the final aggregate becomes relevant.

Common Aggregate Calculation Mistakes

Using the wrong university’s formula

Different universities may use different formulas.

Do not use UNILAG’s formula to calculate your result for UI, UNN, LASU or another institution unless that school has officially adopted the same method.

Using an old formula

An institution may change its screening method from one academic session to another.

Always check the year attached to the calculation method.

Adding scores with different maximum marks

Do not directly add a JAMB score over 400 to a Post-UTME score over 100.

The scores must first be converted to the weights assigned by the institution.

Dividing Post-UTME incorrectly

If the Post-UTME result is already marked over 30 and it contributes 30%, use it directly.

If it is marked over 100 but contributes 30%, convert it to 30%.

Ignoring O’level points

Where O’level results contribute to the aggregate, leaving them out will produce an incomplete result.

Using all O’level subjects

Some institutions score only the five subjects relevant to the selected programme.

Using unrelated subjects may produce the wrong aggregate.

Rounding too early

Do not round every stage of the calculation to a whole number.

Keep decimal figures until the final result unless the institution gives different instructions.

For example:

37.5 + 31.75 = 69.25

Rounding 37.5 to 38 and 31.75 to 32 before adding would produce 70, which is inaccurate.

Confusing percentage with raw score

A Post-UTME score of 24 may mean 24 out of 30, not 24 out of 100.

Check how the result is presented before calculating.

Believing the result guarantees admission

An aggregate above the previous year’s cut-off mark does not guarantee admission for the current session.

Departmental marks may rise or fall depending on competition and available spaces.

What to Do After Calculating Your Aggregate Score

Compare it with official departmental marks

Use only cut-off marks published by the institution for the correct admission session.

Confirm your subject combination

A high aggregate cannot correct an invalid UTME subject combination.

Check your O’level requirements

Ensure you have the compulsory credits for your chosen course.

Upload your O’level result

Candidates with awaiting results must upload them to the JAMB portal before admission can be processed. JAMB CAPS states that awaiting-result candidates must upload their results before being considered for admission.

Monitor JAMB CAPS

JAMB CAPS allows candidates to monitor admission recommendations and respond to provisional offers. It can also display programme transfer information where an institution recommends a candidate for another course.

Consider a course change where necessary

If your aggregate is significantly below the likely requirement for your programme, consider a realistic alternative before the admission exercise closes.

Do not change to a course without checking its subject and O’level requirements.

Avoid admission fraud

Do not pay anyone who promises to increase your aggregate, change your Post-UTME result or manipulate JAMB CAPS.

Use only official school and JAMB platforms.

Frequently Asked Questions

How do I calculate JAMB and Post-UTME aggregate?

When both JAMB and Post-UTME contribute 50%, divide your JAMB score by 8, divide your Post-UTME score by 2 and add the answers.

For example:

JAMB: 280 ÷ 8 = 35

Post-UTME: 70 ÷ 2 = 35

Aggregate: 35 + 35 = 70%

Use this formula only when your institution officially gives 50% to each result.

How do I calculate JAMB score over 50?

Divide your JAMB score by 8.

For example:

300 ÷ 8 = 37.5

Your JAMB contribution is 37.5 out of 50.

How do I convert Post-UTME score to 50%?

When the Post-UTME is marked over 100, divide the score by 2.

For example:

80 ÷ 2 = 40

The contribution is 40 out of 50.

How do I convert Post-UTME score to 30%?

Multiply the score by 0.3 when it is marked over 100.

For example:

70 × 0.3 = 21

The contribution is 21 out of 30.

What is the aggregate of 250 in JAMB and 60 in Post-UTME?

Using the 50:50 formula:

250 ÷ 8 = 31.25

60 ÷ 2 = 30

Aggregate:

31.25 + 30 = 61.25%

What is the aggregate of 300 in JAMB and 75 in Post-UTME?

Using the 50:50 method:

300 ÷ 8 = 37.5

75 ÷ 2 = 37.5

Aggregate:

37.5 + 37.5 = 75%

What is the aggregate of 200 in JAMB and 80 in Post-UTME?

Using the equal-weight method:

200 ÷ 8 = 25

80 ÷ 2 = 40

Aggregate:

25 + 40 = 65%

Can a high Post-UTME score improve a low JAMB score?

Yes, where Post-UTME contributes significantly to the aggregate. However, the candidate must first meet the institution’s minimum JAMB requirement.

Does every university use JAMB divided by eight?

No. Dividing JAMB by eight is appropriate when JAMB contributes 50 marks to an aggregate calculated over 100.

Schools that assign a different weight to JAMB will use a different calculation.

Do polytechnics calculate aggregate scores?

Some polytechnics use screening scores or aggregates, while others may use JAMB and O’level requirements differently. Candidates should check the institution’s official admission guidelines.

Is an aggregate score of 60 good?

It may be competitive for some programmes but too low for others. Compare it with the official departmental cut-off mark for your chosen institution and course.

Is an aggregate score of 70 good?

An aggregate of 70 is generally strong, but it does not guarantee admission into highly competitive courses. The final decision depends on the institution and programme.

Can an institution change its aggregate formula?

Yes. Institutions may review their screening and admission procedures. Always use the method announced for your admission year.

Can I calculate my aggregate before writing Post-UTME?

You cannot calculate the final aggregate without the Post-UTME result where the institution includes Post-UTME.

You can estimate possible outcomes by testing different expected scores.

For example, you can calculate what your aggregate would be if you scored 60, 70 or 80 in Post-UTME.

Conclusion

Calculating your JAMB and Post-UTME aggregate score is simple once you know the formula adopted by your institution.

For schools that give 50% to JAMB and 50% to Post-UTME, divide your JAMB score by eight, divide your Post-UTME score by two and add both results.

For schools that include O’level grades, you must add the official O’level points to the converted JAMB and Post-UTME components.

The most important rule is not to assume that all universities use the same calculation.

Before calculating your score:

1. Visit your institution’s official website.
2. Confirm the formula for the correct academic session.
3. Check the maximum Post-UTME mark.
4. Confirm whether O’level results are included.
5. Calculate each component using its assigned percentage.
6. Compare the final result with the official departmental cut-off mark.

Your aggregate score can help you estimate your admission chances, but it does not replace other requirements. You must also have the correct UTME subject combination, relevant O’level credits and any other qualifications required for your course.

Finally, upload your O’level result, monitor JAMB CAPS and follow only official admission announcements. Careful calculation and timely action can help you avoid mistakes during the 2026 admission exercise.
