COMSATS undergraduate merit is 10% Matric + 40% Intermediate (FSc) + 50% NTS/NAT. In numbers: Merit = (Matric % × 0.10) + (FSc % × 0.40) + (NAT ÷ 100 × 50). This formula is confirmed on COMSATS's own live admissions portal, and every independent source checked agrees with it.

Free · instant · no loginEnter marks and totals exactly as printed on your result cards. Architecture and Art & Design programmes use a different, interview-based process, not this formula.
What NAT score do you need?
Set your target merit and we work backwards from your Matric and FSc marks to the NAT score you need. The grid shows your merit at every score from 50% to 100% of the paper.
COMSATS merit formula
COMSATS undergraduate merit is calculated as:
| Component | Weightage | Marks used |
|---|---|---|
| NTS/NAT (entry test) | 50% | Score on a 100-point scale |
| FSc / Intermediate | 40% | Percentage of total marks |
| Matric / SSC | 10% | Percentage of total marks |
This 10-40-50 split is confirmed on COMSATS's own live admissions portal and is unanimously reported by independent sources, with no evidence of a recent change.
This is the standard formula for regular Intermediate-stream applicants. COMSATS also publishes separate rules for a few specific situations, covered in the next sections.
How to calculate your COMSATS aggregate step by step
- Convert Matric and FSc to percentages. Divide obtained marks by total marks and multiply by 100.
- Take your NAT score as-is. It is already reported on a 100-point scale, so no conversion is needed.
- Multiply by the weightage. NAT × 0.50, FSc percentage × 0.40, Matric percentage × 0.10.
- Add the three numbers. The total is your merit out of 100.
Worked example
A student scores 950/1100 in Matric, 980/1100 in FSc and 75/100 in the NAT.
| Component | Marks | Percentage | Weightage | Points |
|---|---|---|---|---|
| NAT | 75 / 100 | 75.00% | 50% | 37.50 |
| FSc | 980 / 1100 | 89.09% | 40% | 35.64 |
| Matric | 950 / 1100 | 86.36% | 10% | 8.64 |
| Total merit | — | — | 100% | 81.77% |
Try these same numbers in the calculator above and you will get 81.77%.
Special cases: HSSC awaiting, A-Level awaiting and Architecture
COMSATS's own admissions portal publishes three special situations that change how your merit is worked out:
Your HSSC (Intermediate) result has not been announced yet
Submit your First Year (Part-I) marks. Your provisional merit is then calculated as 50% Entry Test + 50% Matric, with Intermediate excluded from the formula until your final result becomes available. Use the “HSSC awaiting” option in the calculator above for this.
You studied A-Levels and your final result is awaited
Your O-Level equivalent marks will be considered as the 50% academic component, alongside 50% for the entry test. Use the “A-Level awaiting” option in the calculator above and enter your O-Level equivalent percentage in the FSc field.
Architecture and Art & Design programmes
These programmes involve an interview, and merit is calculated using a different, unpublished formula from the standard route. If you are applying to one of these programmes, use the Custom option in the calculator with the details from your own admission notice.
The NAT: test structure and scoring
The NAT (National Aptitude Test) is run by NTS (National Testing Service), not by COMSATS itself, and is used by many universities across Pakistan, not only COMSATS.
- The standard NAT has around 90 MCQs and is scored on a 100-point scale, which is the number you enter directly into the calculator above.
- There are several NAT categories depending on your academic background and target programme (for example, pre-engineering, pre-medical, computer science and general science streams), and the subject mix differs between them.
- A typical section breakdown includes English, Analytical/Quantitative Reasoning, and a subject-specific section based on your FSc stream, though the exact split varies by category.
- The standard scheduled NAT is widely reported as having no negative marking, though NTS could change this, and some customised NAT tests run for specific employers or purposes do use negative marking.
- Your NAT score is typically valid for one year from the result date.
Because NAT categories and their exact section weightings vary, treat the numbers above as a general guide and confirm the specific pattern for your chosen category on the NTS website or in your COMSATS admission notice.
Which NAT category matches your programme?
Widely reported category-to-programme mapping, based on your Intermediate stream:
| NAT category | Intermediate stream | Typical programmes |
|---|---|---|
| NAT-IE | Pre-Engineering (Maths, Physics, Chemistry) | Engineering programmes |
| NAT-ICS | ICS (Maths, Physics, Computer) | Computer Science, Software Engineering, AI, Cyber Security |
| NAT-IM | Pre-Medical (Biology, Physics, Chemistry) | Programmes accepting a Pre-Medical background |
| NAT-IGS / NAT-ICOM | General Science / Commerce | General Science, Business and Commerce-linked programmes |
This mapping is reported consistently across independent sources, though not stated word-for-word on COMSATS's own portal. Confirm your exact category when you register for the NAT.
How much does each mark move your merit?
With the NAT carrying half the total weight, and scored out of only 100, it moves your merit fastest per raw mark.
| Improvement | Change in merit |
|---|---|
| +1 mark in the NAT (out of 100) | +0.5 points |
| +10 marks in FSc (out of 1100) | +0.364 points |
| +10 marks in Matric (out of 1100) | +0.091 points |
A single extra NAT mark is worth roughly as much as 14 extra FSc marks, and more than 50 extra Matric marks. If you are deciding where to focus your remaining preparation time, the NAT is almost always the better use of it.
COMSATS eligibility: minimum marks
Widely reported minimums for COMSATS undergraduate admission:
- At least 60% marks in Intermediate (FSc) or an equivalent qualification.
- At least 50% in the NAT to be considered eligible at all, regardless of your academic marks.
Exact eligibility can vary slightly by programme and campus. Confirm the current requirement for your specific programme on the COMSATS admissions portal before you apply.
COMSATS campuses this formula covers
COMSATS University Islamabad currently takes regular undergraduate admission through the 10-40-50 merit formula at seven campuses, all applying through the same central admissions portal:
- Islamabad
- Abbottabad
- Lahore
- Sahiwal
- Wah
- Attock
- Vehari
COMSATS also has a Virtual Campus, which has not yet opened regular undergraduate merit-based admission in the same way as the seven campuses above — its first undergraduate programmes are expected to launch from Spring 2027, subject to HEC approval. Check the Virtual Campus's own admissions page before assuming the same formula and process apply there.
Seat availability, closing merit and programme offerings differ by campus, so compare more than one location when you are choosing your preferences.
What merit do you need for COMSATS?
There is no single number: closing merit depends on the programme, the campus and the strength of that year's applicant pool. Computer Science and Software Engineering at the Islamabad campus are typically the most competitive, and other programmes and campuses close lower.
Rather than rely on one quoted figure, use the previous cycle's official closing merit for your programme and campus as your target, then use the required-score tool above to see the NAT score you need to reach it.
How to improve your COMSATS merit
- Prioritise the NAT. At 50% weightage and only 100 total marks, it has by far the biggest effect on your aggregate per mark.
- Register for your correct NAT category. The subject mix depends on your academic background and target programme, so check which category matches your case before you register.
- Do not neglect FSc. At 40% weightage it still matters more than Matric, and a strong Intermediate result gives you a buffer if the NAT does not go perfectly.
- Watch the special-case rules. If your HSSC or A-Level result is still pending, know which provisional formula applies to you before you submit your application.
- Compare campuses. The same NAT score can put you into a programme at one campus and miss it at another.
- Apply broadly. Consider more than one university so a single test day does not decide your whole year.
Common mistakes when calculating COMSATS aggregate
- Treating the NAT score as a percentage of a 200 or 400 total. It is already on a 100-point scale.
- Averaging the three components. The NAT is weighted 50%, so a simple average gives the wrong answer.
- Including Intermediate marks for HSSC-awaiting candidates. That route uses 50% Entry Test + 50% Matric only.
- Using self-calculated O-Level marks instead of the equivalence certificate figure for A-Level-awaiting applicants.
- Assuming Architecture or Art & Design uses the standard formula. They use an interview-based process instead.
- Treating the estimate as final. Only COMSATS's own merit list is official.
Frequently asked questions
What is the COMSATS merit formula?
COMSATS undergraduate merit is 10% Matric, 40% Intermediate (FSc) and 50% NTS/NAT. In numbers: (Matric % x 0.10) + (FSc % x 0.40) + (NAT / 100 x 50). This is confirmed directly on COMSATS's own admissions portal.
How is the COMSATS aggregate calculated?
Convert your Matric and FSc marks to percentages, take your NAT score as-is since it is already out of 100, then apply the weightage and add the results. For example, Matric 950/1100, FSc 980/1100 and NAT 75/100 give 8.64 + 35.64 + 37.50 = 81.77%.
How many marks is the NAT out of?
The standard NAT has around 90 MCQs and is scored on a 100-point scale. Enter your score directly out of 100 in the calculator.
What happens if my HSSC result is not announced yet?
Submit your First Year (Part-I) marks. COMSATS calculates your provisional merit as 50% Entry Test plus 50% Matric, excluding Intermediate until your final result is available. Use the HSSC awaiting option in the calculator.
What happens if I studied A-Levels and my final result is awaited?
Your O-Level equivalent marks are considered as the 50% academic component alongside 50% for the entry test. Use the A-Level awaiting option in the calculator and enter your O-Level equivalent percentage.
Do Architecture and Art & Design programmes use the same formula?
No. These programmes involve an interview and a different, unpublished formula. Use the Custom weightage option in the calculator with the figures from your own admission notice if you are applying to one of these programmes.
What is the minimum eligibility for COMSATS?
Widely reported minimums are at least 60% in Intermediate (FSc) or equivalent, and at least 50% in the NAT to be eligible at all.
Is there negative marking in the NAT?
The standard scheduled NAT is widely reported as having no negative marking, though this could change and some customised NAT tests used for other purposes do apply negative marking. Confirm the current policy for your test date.
How much does the NAT matter compared with FSc and Matric?
A great deal. One extra NAT mark is worth roughly as much as 14 extra FSc marks and more than 50 extra Matric marks, because the NAT is weighted 50% but scored out of only 100.
What NAT score do I need to reach a target merit?
Subtract your Matric and FSc points from your target and divide by 0.50. For example, with Matric 950/1100 and FSc 980/1100 you already have 44.27 points, so a target of 75% needs a NAT score of at least 62/100. Use the required-score tool on this page to do it for your own marks.
Which campuses does this formula apply to?
The 10-40-50 formula applies to COMSATS's regular undergraduate admission at its seven campuses: Islamabad, Abbottabad, Lahore, Sahiwal, Wah, Attock and Vehari. Its Virtual Campus has not yet opened the same regular merit-based undergraduate admission, with its first undergraduate programmes expected from Spring 2027.
Which NAT category should I register for?
It depends on your Intermediate stream: Pre-Engineering candidates typically take NAT-IE, ICS candidates take NAT-ICS, Pre-Medical candidates take NAT-IM, and General Science or Commerce candidates take NAT-IGS or NAT-ICOM. Confirm the category that matches your target programme before you register.
What merit do I need to get into COMSATS?
It depends on the programme, campus and applicant pool that year, so there is no fixed number. Use the previous cycle's official closing merit for your programme and campus as a target, then use the required-score tool to see the NAT score you need.
Is this the official COMSATS merit?
No. This is an independent estimator. Your official merit position is published by COMSATS on its admissions portal for your campus.
Why is my merit different from the one COMSATS published?
Common reasons are applying the wrong special-case rule (HSSC or A-Level awaiting), using the wrong NAT total, forgetting that Architecture/Art & Design use a different process, or rounding. Recheck against the official notice for your category.
