How To Calculate Post UTME Screening Score:- Many candidates who complete their JAMB examination and Post UTME screening still have one important question: How is the Post UTME screening score calculated?

This question is important because your JAMB score and Post UTME score are not always used as separate figures when a university ranks candidates for admission. Depending on the institution, your UTME score may be combined with your Post UTME score, O’Level result, or other screening components to produce an aggregate score.

However, there is no single Post UTME screening formula used by every university in Nigeria. JAMB has explained that institutions may combine UTME, Post-UTME or other screening results, O’Level grades and, in some cases, other parameters when ranking candidates.

Therefore, before calculating your score, you must first know the formula used by your university for the relevant admission session.

This article explains how to calculate Post UTME screening score, the most common formulas, worked examples, how to convert JAMB and Post UTME scores into weighted percentages, how O’Level results may be included, and why you should not use another university’s formula for your own institution.

How Do You Calculate Post UTME Screening Score?

The basic calculation depends on the university’s approved weighting system.

For a university using a 50% JAMB + 50% Post UTME formula:

Aggregate Score = (JAMB Score ÷ 8) + (Post UTME Score ÷ 2)

For example:

• JAMB score = 280
• Post UTME score = 70

JAMB contribution:

280 ÷ 8 = 35

Post UTME contribution:

70 ÷ 2 = 35

Final aggregate:

35 + 35 = 70%

However, some universities use different weightings, such as 60% JAMB + 40% Post UTME, while others may include O’Level results or other screening components.

So, the most important rule is:

Use the formula officially prescribed by your university for your admission year and programme.

What Is a Post UTME Screening Score?

A Post UTME screening score is the result obtained from the screening process used by a university after candidates have taken the UTME.

Depending on the institution, Post UTME screening may involve:

• a computer-based test;
• an online screening exercise;
• physical screening;
• document verification;
• calculation based on JAMB and O’Level results;
• or a combination of different admission screening components.

This means the term Post UTME screening score can mean different things at different universities.

For universities that conduct an actual Post UTME examination, the candidate may receive a score based on performance in that test.

For universities that conduct screening without a separate examination, the institution may calculate a screening or aggregate score from the candidate’s existing qualifications.

What Is an Aggregate Score?

An aggregate score is the combined score obtained after the university applies its approved weighting system to the relevant admission components.

For example, a university could decide that:

• JAMB = 50%
• Post UTME = 50%

In that situation, both components contribute equally to the final score.

Another institution could use:

• JAMB = 60%
• Post UTME = 40%

Here, the JAMB score contributes more to the final aggregate.

Some institutions may also include O’Level performance or other screening criteria.

JAMB has stated that there is no single uniform admission cut-off score applicable to every institution and that institutions can determine their admission ranking using multiple components.

Why Is It Important to Know Your Aggregate Score?

Knowing how your screening score is calculated can help you understand your position during the admission process.

It can help you:

• estimate your final aggregate;
• understand how your JAMB score affects admission;
• know how much your Post UTME performance contributes;
• compare your score with an institution’s published benchmark;
• avoid using the wrong calculation formula;
• identify errors in a result released by the institution;
• understand why a candidate with a higher JAMB score may not necessarily have the highest aggregate.

For example, two candidates can have different JAMB and Post UTME scores but end up with similar aggregate scores after weighting.

The Most Common Post UTME Screening Formula: 50% JAMB + 50% Post UTME

One commonly encountered system gives equal weight to JAMB and Post UTME.

Under this system:

JAMB = 50%

Post UTME = 50%

Because JAMB is scored out of 400, it must first be converted to a score out of 50.

JAMB Contribution

JAMB Score ÷ 8

Because:

400 ÷ 8 = 50

Post UTME Contribution

If the Post UTME score is out of 100:

Post UTME Score ÷ 2

Because:

100 ÷ 2 = 50

Complete Formula

Aggregate Score = (JAMB Score ÷ 8) + (Post UTME Score ÷ 2)

Example 1: JAMB 280 and Post UTME 70

Suppose a candidate has:

JAMB = 280

Post UTME = 70

Step 1: Calculate JAMB contribution

280 ÷ 8 = 35

Step 2: Calculate Post UTME contribution

70 ÷ 2 = 35

Step 3: Add the two scores

35 + 35 = 70

Therefore:

Aggregate Score = 70%

Example 2: JAMB 250 and Post UTME 65

JAMB:

250 ÷ 8 = 31.25

Post UTME:

65 ÷ 2 = 32.5

Aggregate:

31.25 + 32.5 = 63.75%

Therefore, the candidate’s aggregate score is:

63.75%

Example 3: JAMB 300 and Post UTME 80

JAMB:

300 ÷ 8 = 37.5

Post UTME:

80 ÷ 2 = 40

Aggregate:

37.5 + 40 = 77.5%

Therefore:

Final Aggregate = 77.5%

How To Calculate a 60% JAMB + 40% Post UTME Score

Not every university uses the 50:50 method.

Suppose your institution uses:

• JAMB = 60%
• Post UTME = 40%

You should convert each score according to its assigned weight.

Formula

JAMB Contribution = (JAMB Score ÷ 400) × 60

Post UTME Contribution = (Post UTME Score ÷ 100) × 40

Then:

Aggregate = JAMB Contribution + Post UTME Contribution

Example: JAMB 280 and Post UTME 70 Using 60:40

Step 1: JAMB contribution

280 ÷ 400 × 60

= 0.70 × 60

= 42

Step 2: Post UTME contribution

70 ÷ 100 × 40

= 0.70 × 40

= 28

Step 3: Add the contributions

42 + 28 = 70

Therefore:

Aggregate Score = 70%

Notice that this particular example produces the same final score as the 50:50 method because both raw scores represent 70% of their respective maximums.

Another 60:40 Example

Suppose:

• JAMB = 320
• Post UTME = 60

JAMB contribution:

320 ÷ 400 × 60 = 48

Post UTME contribution:

60 ÷ 100 × 40 = 24

Final aggregate:

48 + 24 = 72%

Therefore:

Aggregate Score = 72%

General Formula for Any JAMB and Post UTME Weighting

If your university publishes a weighting system, you can calculate it using this general method.

JAMB contribution

(JAMB Score ÷ 400) × JAMB Weight

Post UTME contribution

(Post UTME Score ÷ Maximum Post UTME Score) × Post UTME Weight

Then:

Final Aggregate = JAMB Contribution + Post UTME Contribution

For example, if the university assigns 60% to JAMB and 40% to Post UTME:

(JAMB ÷ 400 × 60) + (Post UTME ÷ 100 × 40)

This method is particularly useful because not every institution uses exactly the same weighting system.

What If the Post UTME Test Is Not Marked Out of 100?

This is another important issue.

Some Post UTME examinations may have a different number of questions or a different raw scoring system.

For example, imagine a screening test has a maximum score of 50.

If you score 40 out of 50 and the university wants the Post UTME component converted to 40%, the calculation would be:

40 ÷ 50 × 40

= 32

Therefore, your Post UTME contribution is 32 out of 40.

The important thing is to use the actual maximum score specified by the university.

Do not automatically divide every Post UTME score by 2 unless the institution has confirmed that the score is out of 100 and carries a 50% weight.

How To Calculate Post UTME Score as a Percentage

If you simply want to convert your raw Post UTME score into a percentage, use:

Percentage = (Score Obtained ÷ Maximum Score) × 100

Example

If you scored 36 out of 50:

36 ÷ 50 × 100

= 72%

Therefore, your Post UTME percentage is 72%.

This is different from your final aggregate score.

Your Post UTME percentage tells you how you performed in the screening test, while your aggregate score combines that performance with other admission components.

Difference Between Post UTME Score and Aggregate Score

These terms are often used interchangeably, but they can mean different things.

Post UTME Score

This normally refers to the score obtained from the Post UTME examination or screening component.

Example:

Post UTME = 72/100

Aggregate Score

This is the combined score after applying the university’s weighting system.

Example:

JAMB contribution = 38

Post UTME contribution = 36

Aggregate = 74%

Therefore:

Post UTME score = 72

while:

Aggregate score = 74%

The exact calculation depends on the institution.

Does O’Level Result Count in Post UTME Screening Score?

It can.

Some universities use O’Level results as part of their screening or aggregate calculation, while others use them mainly to determine eligibility.

JAMB has noted that O’Level grades can be one of the parameters used alongside UTME and Post-UTME or other screening results in determining candidates’ eventual ranking.

Therefore, you should not assume that every university calculates aggregate scores using only JAMB and Post UTME.

How O’Level Grades May Be Included

Where an institution assigns points to O’Level grades, it may specify:

• the subjects to be considered;
• the number of subjects;
• the points awarded for each grade;
• whether one or two sittings are accepted;
• whether the grades contribute directly to the aggregate;
• or whether they are used only as an eligibility requirement.

For example, an institution could publish its own point system for grades such as:

• A1
• B2
• B3
• C4
• C5
• C6

However, there is no universal O’Level point system that every Nigerian university must use.

This is why candidates should never copy an O’Level formula from another institution without checking their own university’s admission guidelines.

Example of a Screening Formula That Includes O’Level

Suppose a university officially assigns:

• JAMB = 70%
• O’Level = 30%

A candidate has:

JAMB = 273

Suppose the university’s published O’Level point system gives the candidate 24 points out of a possible 40.

JAMB contribution

273 ÷ 400 × 70

= 47.775

O’Level contribution

24 ÷ 40 × 30

= 18

Final aggregate

47.775 + 18

= 65.775

Rounded to two decimal places:

65.78%

This example demonstrates why you must use the exact point system published by your university.

Is There One Universal Post UTME Screening Formula in Nigeria?

No.

This is one of the most important things candidates should understand.

Universities have different admission screening procedures and may change their formulas from one admission session to another.

JAMB has explicitly stated that institutions can use multiple components when determining the eventual aggregate and ranking of candidates.

For example, one university may use:

50% JAMB + 50% Post UTME

Another may use:

60% JAMB + 40% Post UTME

Another may include O’Level results.

Another institution may not conduct a conventional Post UTME examination at all.

Therefore, there is no single formula that should be applied to every Nigerian university.

Why You Should Not Use Another University’s Formula

Imagine you applied to University A, but you use University B’s aggregate formula.

You could calculate your score incorrectly even if your mathematics is perfect.

For example:

University A:

50% JAMB + 50% Post UTME

University B:

60% JAMB + 40% Post UTME

If you use University B’s formula for University A, the final result may be different.

Therefore, always identify the institution first.

How To Find Your University’s Correct Formula

Before calculating your Post UTME screening score:

Step 1: Visit the university’s official website

Avoid relying only on social media posts or third-party calculators.

Step 2: Find the current admission notice

Look for the current Post UTME or admission screening guidelines.

Step 3: Check the screening method

Find out whether the university conducts:

• CBT;
• online screening;
• physical screening;
• or another form of assessment.

Step 4: Look for the scoring method

Check whether the university states:

• JAMB percentage;
• Post UTME percentage;
• O’Level percentage;
• departmental weighting;
• or another scoring method.

Step 5: Use the published formula

Only after confirming the formula should you calculate your aggregate.

Can I Calculate My Post UTME Screening Score Before the Result Is Released?

Yes, if you know the scores or information required by the university’s formula.

For example, if your university uses JAMB and Post UTME only, you can calculate the aggregate once you know both scores.

If O’Level grades are included, you will also need the relevant grades and the institution’s point system.

However, an estimated calculation should not be treated as your official admission aggregate until the institution releases or confirms it.

Can a High JAMB Score Guarantee a High Aggregate?

No.

A high JAMB score can give you a strong starting position, but the final aggregate depends on the formula used by your institution.

For example, under a 50:50 system:

Candidate A:

• JAMB = 300
• Post UTME = 50

Candidate B:

• JAMB = 260
• Post UTME = 80

Candidate A:

300 ÷ 8 = 37.5

50 ÷ 2 = 25

Aggregate = 62.5

Candidate B:

260 ÷ 8 = 32.5

80 ÷ 2 = 40

Aggregate = 72.5

In this example, Candidate B has a lower JAMB score but a higher final aggregate because of the stronger Post UTME performance.

This is why candidates should prepare seriously for the screening stage instead of assuming that a strong UTME score automatically guarantees admission.

How Much Does One Extra Post UTME Mark Add to Your Aggregate?

This depends on the weighting system.

Under a 50% Post UTME weighting, where the Post UTME is scored out of 100:

1 Post UTME mark = 0.5 aggregate point

Therefore:

• 2 extra Post UTME marks = 1 aggregate point
• 10 extra Post UTME marks = 5 aggregate points
• 20 extra Post UTME marks = 10 aggregate points

Under a 40% Post UTME weighting:

1 Post UTME mark = 0.4 aggregate point

This demonstrates why the weighting system matters.

How Much Does One JAMB Mark Add to Your Aggregate?

Under a 50% JAMB weighting:

JAMB is out of 400.

Therefore:

1 JAMB mark = 1 ÷ 8 = 0.125 aggregate point

So:

• 8 JAMB marks = 1 aggregate point
• 40 JAMB marks = 5 aggregate points
• 80 JAMB marks = 10 aggregate points

Again, this applies only to a 50% JAMB weighting system.

If the university uses 60% JAMB, the contribution is different.

Post UTME Screening Score Example Table

For a university using the 50:50 formula:

JAMB Score	Post UTME Score	JAMB Contribution	Post UTME Contribution	Aggregate
200	50	25	25	50
220	60	27.5	30	57.5
240	65	30	32.5	62.5
260	70	32.5	35	67.5
280	75	35	37.5	72.5
300	80	37.5	40	77.5
320	85	40	42.5	82.5
340	90	42.5	45	87.5

These figures are examples based specifically on the 50:50 formula and should not be treated as the official formula for every university.

What Is a Good Post UTME Aggregate Score?

There is no single aggregate score that guarantees admission into every university or course.

A score that may be competitive for one programme may not be sufficient for another.

Admission competitiveness can depend on:

• university;
• course;
• number of applicants;
• available spaces;
• UTME performance;
• Post UTME performance;
• O’Level requirements;
• admission category;
• and the institution’s ranking method.

Therefore, candidates should focus on achieving the highest score possible rather than relying on a universal “good aggregate score.”

Does Post UTME Aggregate Score Determine Admission?

It can be an important part of admission ranking, but the exact process depends on the institution.

JAMB has explained that institutions use the relevant admission parameters to arrive at an eventual ranking of candidates.

A candidate may still need to satisfy other requirements, including:

• correct JAMB subject combination;
• required O’Level subjects;
• minimum institutional requirements;
• course-specific requirements;
• successful screening;
• and other conditions published by the institution.

Therefore, your aggregate score should not be viewed in isolation.

Common Mistakes Candidates Make When Calculating Aggregate Score

1. Assuming Every University Uses 50:50

This is one of the most common mistakes.

The 50:50 formula is only applicable where the institution uses that weighting.

2. Dividing Every Post UTME Score by 2

You should only divide by 2 when the university’s formula converts a score out of 100 into a 50% component.

3. Ignoring O’Level Requirements

Some institutions may include O’Level grades in their screening calculations.

4. Using the Wrong Maximum Score

If the Post UTME test is not out of 100, you must use the actual maximum score or the conversion method specified by the university.

5. Using an Old Formula

Universities can change their screening procedures between admission sessions.

Always check the current admission guidelines.

6. Treating an Online Calculator as Official

A calculator can help with mathematics, but it cannot replace the university’s official admission guidelines.

How To Calculate Post UTME Score Without Making Mistakes

Use this simple procedure:

1. Find your JAMB score.

2. Find your Post UTME score.

3. Find the maximum Post UTME score.

4. Find the university’s official weighting system.

5. Convert the JAMB score according to its weight.

6. Convert the Post UTME score according to its weight.

7. Add the weighted contributions.

8. Include O’Level points only if the university’s formula requires them.

9. Round the final answer only according to the institution’s stated method.

10. Compare the result with official admission information, not rumors.

Simple Post UTME Aggregate Calculator Formula

You can use the following general formula whenever the institution gives a percentage weight for each component:

JAMB Contribution

(JAMB Score ÷ 400) × JAMB Weight

Post UTME Contribution

(Post UTME Score ÷ Maximum Post UTME Score) × Post UTME Weight

O’Level Contribution

(Your O’Level Points ÷ Maximum O’Level Points) × O’Level Weight

Final Aggregate

JAMB Contribution + Post UTME Contribution + O’Level Contribution

Only include the O’Level component when the university officially includes it.

Frequently Asked Questions

How is Post UTME screening score calculated?

It depends on the university. A common system combines JAMB and Post UTME using a 50:50 weighting, while other institutions may use different percentages or include O’Level results.

What is the formula for 50% JAMB and 50% Post UTME?

The formula is:

Aggregate = (JAMB ÷ 8) + (Post UTME ÷ 2)

when both JAMB is out of 400 and Post UTME is out of 100.

How do I calculate 60% JAMB and 40% Post UTME?

Use:

Aggregate = (JAMB ÷ 400 × 60) + (Post UTME ÷ 100 × 40)

if the Post UTME score is out of 100.

Is Post UTME score the same as aggregate score?

No. Post UTME score generally refers to your performance in the screening test, while aggregate score is the combined weighted result of the admission components used by the university.

Does JAMB score count in Post UTME aggregate?

In many institutions, yes. However, the percentage assigned to JAMB differs from one university to another.

Does WAEC or NECO count in aggregate score?

Some universities include O’Level performance in their screening calculation, while others use it mainly as an eligibility requirement.

Can I calculate my aggregate score myself?

Yes. If you know the official formula and the required scores, you can calculate it yourself.

What if my university has not published its formula?

Do not assume another university’s formula applies. Wait for the institution’s official screening or admission guidelines or contact the institution through its official channel.

Can a candidate with a lower JAMB score have a higher aggregate?

Yes. If the institution combines JAMB and Post UTME scores, a stronger Post UTME performance can compensate for part of the difference, depending on the weighting system.

Does a high aggregate guarantee admission?

No. Admission also depends on the institution, course, available spaces, eligibility requirements, candidate ranking and other applicable admission conditions.

Conclusion

Learning how to calculate Post UTME screening score is important because your JAMB score is not necessarily the same as your final admission aggregate.

The correct calculation depends on the university’s official screening method.

For a 50:50 JAMB and Post UTME system, the calculation is:

Aggregate = (JAMB ÷ 8) + (Post UTME ÷ 2)

For a 60:40 system, the calculation is:

Aggregate = (JAMB ÷ 400 × 60) + (Post UTME ÷ 100 × 40)

Where O’Level results are included, the university’s specific O’Level point system must also be applied.

The most important thing to remember is that there is no universal Post UTME aggregate formula for all Nigerian universities. JAMB itself recognizes that institutions may combine different admission parameters when ranking candidates.

Therefore, always confirm the formula for your specific university, course and admission session before calculating your score.

A correct calculation can help you understand your admission position, but it should not be confused with an admission guarantee.
