What is "Aggregate Score" for University Admissions?
An aggregate score (or cumulative score), is a calculated numerical representation of a student’s academic performance and qualifications. Universities and colleges use aggregate scores as a key criterion for admission to undergraduate programs. The aggregate score takes into account various factors, including your secondary school exam results (O’levels), your JAMB UTME result, and sometimes additional components like post-UTME exams or screening excercise.
Since the introduction of JAMB CAPS, every school is required to make JAMB score weigh at least 50% of the total aggregate score of their candidates.
On this page you will find our Aggregare Score Calculator to easily and automatically calculate your score, as well as steps to calculate your score manually.
Step 1
Gather Required Information
Before you can calculate your aggregate score, you need to collect the necessary information, which typically includes:
Secondary School Results: Obtain your final exam results, such as your West African Senior School Certificate Examination (WASSCE), Senior Secondary Certificate Examination (SSCE), or equivalent.
Subject Relevance: Determine the relevant subjects needed to study your intended course. This information is often provided by the university or college you’re applying to.
Grading System: Calculating the grade points used for your secondary school exams. Typically, this includes letter grades (e.g., A, B, C) and corresponding grade points (e.g., 10, 9, 8).
Step 2
Assign Grade Points
Typically the most common points system is as follows:
| GRADE | POINTS |
|---|---|
| A1 | 10 |
| A2 (B2) | 9 |
| B3 | 8 |
| C4 | 7 |
| C5 | 6 |
| C6 | 5 |
Assign grade points to your secondary school exam results based on the grading system.
Example Application:
- If a student has grades of A1 in five subjects, their total O’Level points would be 10 × 5 = 50 points.
- If another student has grades of B2, B3, C4, C5, and C6, their O’Level points would be 9 + 8 + 7 + 6 + 5 = points.
Step 3
University Score weighting & Formula
Different universities and programs use varying methods/formulas to calculate your aggregate score for admission. Always check with the specific university for the most up-to-date and accurate formula, as these can change from year to year or even vary by department.
The general weight distributions used for calculating aggregate scores in Nigerian universities typically involves combining the scores from three components: UTME , Post-UTME (if applicable), and O’Level results. Below are the most common distributions:
Formula:
$$\left(\frac{\text{UTME Score}}{8}\right) + \left(\frac{\text{Post-UTME}}{40} \times 30\right) + \left(\frac{\text{O’level points}}{2.5}\right)$$
- UTME Score: 50% (UTME score divided by 8)
- Post-UTME Score: 30% (Post-UTME score divided by number of questions, and multiplied by the %)
- O’Level Results: 20% (O’Level points divided by 2.5)
Formula:
$$\left(\frac{\text{UTME}}{8}\right) + \left(\frac{\text{Post-UTME}}{4}\right) + \left(\frac{\text{O’Level Points}}{2}\right)$$
- UTME Score: Dividing the UTME score by 8 scales it from a maximum of 400 to 50.
- Post-UTME Score: Dividing the Post-UTME score (typically out of 100) by 4 scales it to 25.
- O’Level Points: Dividing by 2 scales the O’Level points from a maximum of 50 to 25.
Formula:
$$\left(\frac{\text{UTME}}{400} \times 60\right) + \left(\frac{\text{Post-UTME}}{2.5}\right)$$
- UTME Score: The UTME score is divided by 400 (the total possible score) and then multiplied by 60 to reflect its 60% contribution.
- Post-UTME Score: The Post-UTME score is typically out of 100. To simplify the calculation while ensuring a 40% contribution, the score is divided by 2.5. This scaling converts the Post-UTME score to a 40% weight directly.
Note: O’Level results might not be explicitly included or may be considered separately.
Formula:
$$\left(\frac{\text{UTME}}{8}\right) + \left(\frac{\text{Post-UTME}}{2}\right)$$
- UTME Score: 50% (UTME score divided by 8)
- Post-UTME Score: 50% (Post-UTME score divided by 2)
Note: Some universities use only UTME and Post-UTME scores, with no explicit O’Level contribution.
- UTME Score: 50% (UTME score divided by 8)
- O’level Score: 50% (O’Level points calculated based on the university’s point system)
Formula:
$$\left(\frac{\text{UTME}}{4}\right) + \left(\text{O’Level Points} \times 0.3\right)$$
- UTME Score: 70% (UTME score divided by 4)
- O’Level Results: 30% (O’Level points calculated based on the university’s point system)
Note: Used by institutions that do not conduct Post-UTME exams.
- UTME Score: 100% (UTME score)
Note: Used by some institutions that do not conduct Post-UTME and rely solely on UTME scores, with O’Level results being used for eligibility only, not for aggregate calculation.
These distributions reflect the general patterns, but universities may modify these weights depending on the academic session or specific program requirements. Always verify with the institution to confirm the current and applicable weight distribution.
Examples of Weight Distribution by University:
- University of Lagos (UNILAG): Uses a 50% UTME, 30% Post-UTME, and 20% O’Level distribution.
- University of Nigeria, Nsukka (UNN): Uses a 60-40 distribution, with 60% allocated to the UTME score and 40% to the Post-UTME score, with the O’Level score serving as an eligibility criterion.
Step 4
Assign formula & calculate score
Example Application:
For instance, if a university uses a 50-30-20 weight distribution for UTME, Post-UTME, and O’Level respectively:
Aggregate Score= $$\left(\frac{\text{UTME}}{8}\right) + \left(\text{Post-UTME} \times 0.3\right) + \left(\frac{\text{O’Level}}{2.5}\right)$$
Breakdown:
- UTME Score Contribution:
- The UTME score is divided by 8 to convert the score (out of 400) into a percentage of 50%.
- Post-UTME Score Contribution:
- The Post-UTME score (if applicable) is typically weighted at 30%. The exact weight may vary depending on the institution.
- O’Level Points Contribution:
- The O’Level points (calculated based on the grades in the best 5 subjects) are sometimes divided by 2.5 to convert them into a percentage, usually contributing 20% to the final aggregate score.
This formula can vary slightly depending on the university’s specific requirements. Some universities may exclude the Post-UTME score and adjust the weights accordingly between the UTME score and O’Level points. Others might have different point systems for O’Level grades.
