Detailed Formulas with Worked Examples
UET Lahore Aggregate Formula (2026)
$$Aggregate = \left(\frac{Matric}{1200} \times 17\right) + \left(\frac{FSc}{1200} \times 50\right) + \left(\frac{ECAT}{400} \times 33\right)$$
Example: Matric: 980/1200, FSc: 950/1200, ECAT: 340/400
$$= \left(\frac{980}{1200} \times 17\right) + \left(\frac{950}{1200} \times 50\right) + \left(\frac{340}{400} \times 33\right) = 13.88 + 39.58 + 28.05 = \mathbf{81.51%}$$
Note: UET Lahore weights FSc heavily at 50%. Students with strong FSc (90%+) have a significant advantage here. Calculate your UET merit →
NUST Aggregate Formula (2026 — NET)
$$Aggregate = (Matric \times 0.10) + (FSc \times 0.15) + (NET \times 0.75)$$
NUST uses its own NET (NUST Entry Test), not ECAT. The NET has 200 marks — 75% of admission weight.
Example: Matric: 1020/1100, FSc: 990/1100, NET: 155/200
$$= 9.27 + 13.50 + 58.13 = \mathbf{80.90%}$$
Strong NET performance is critical at NUST. Students who are good at standardized tests should prioritize NUST. Calculate your NUST merit →
GIKI Aggregate Formula (2026 — GES)
$$Aggregate = (Matric \times 0.10) + (FSc \times 0.30) + (GES \times 0.60)$$
GIKI accepts ECAT scores directly as GES (GAT Engineering Score). It has the second-highest entry test weight among top universities.
COMSATS University Aggregate Formula (2026)
$$Aggregate = (Matric \times 0.10) + (FSc \times 0.40) + (Entry\ Test \times 0.50)$$
COMSATS accepts both ECAT and NAT-IE. Students who couldn't appear in ECAT can use NAT-IE. This is one of COMSATS's most student-friendly admission policies.

PIEAS Aggregate Formula (2026)
$$Aggregate = (Matric \times 0.15) + (FSc \times 0.25) + (PIEAS\ Test \times 0.60)$$
PIEAS is the most selective engineering university in Pakistan. It also offers full stipends to admitted students, making it effectively free for the 100-150 students admitted per year.
FAST-NUCES Aggregate Formula (2026)
$$Aggregate = (Matric \times 0.10) + (FSc \times 0.40) + (FAST\ Test \times 0.50)$$
FAST uses its own entry test (not ECAT). The FAST test focuses heavily on Mathematics and aptitude.

What If My FSc Is Below 60%? — Admission Strategy
If your FSc percentage is weak (below 65%), here's your strategy:
| Your Weakness | Best University Choices | Reason |
|---|---|---|
| Weak FSc (55-65%) | NUST, GIKI | Test weight 60-75% — FSc matters less |
| Weak Entry Test | UET Lahore | FSc weighted at 50% — reduces test impact |
| Both weak | COMSATS (non-ISB campus) | Lower closing merit, wider intake |
| Only Matric weak | Any — Matric is 10-17% max | Matric weight is lowest everywhere |
Key insight: If you score 350+/400 on ECAT, you can compensate for average FSc marks at most universities. Use our merit calculator to find which universities you're currently eligible for.
Which University Gives the Most Weight to FSc?
UET Lahore (50%) gives the highest FSc weight. If you have 90%+ FSc, UET Lahore is your most strategic choice because FSc marks contribute more to your aggregate than at NUST or GIKI.
Students with 85%+ FSc who score reasonably on ECAT (280-310/400) are often surprised to find they qualify for COMSATS Islamabad CS — which has a lower closing merit (82.1%) than NUST but excellent CS programs.
Frequently Asked Questions
When is ECAT 2026?
ECAT 2026 is expected in July-August 2026, with registration typically opening in May-June. Check our test preparation page for official date announcements.
Is ECAT compulsory for COMSATS University?
No. COMSATS accepts both ECAT and NAT-IE (National Aptitude Test for Engineering). The aggregate formula is the same regardless of which test score you submit.
Which university gives the most weight to FSc for engineering?
UET Lahore gives 50% weight to FSc — the highest among major engineering universities. Students with 90%+ FSc should strongly consider UET Lahore.
Can I use NAT instead of ECAT?
Yes. COMSATS, some UET campuses, and several other universities accept NAT-IE. Check each university's specific admission criteria — the aggregate formula typically remains unchanged.
What is a good ECAT score for top universities?
- NUST (via NET, not ECAT): 150+/200 — extremely competitive
- UET Lahore: 300+/400 to be competitive for CS
- COMSATS Islamabad CS: 260+/400 (merit fluctuates annually)
- GIKI: 290+/400
Use our merit calculator with your specific Matric/FSc marks to calculate the exact ECAT score you need for each university.
How do I convert A-Level grades to Pakistani aggregate?
Most universities use: A* = 90%, A = 85%, B = 75%, C = 65%, D = 55%. Some universities have their own equivalence formulas. Contact the specific university's admissions office to confirm their official A-Level equivalence table before applying.
How to Maximize Your ECAT Aggregate
- NUST/GIKI strategy: Focus heavily on entry test (60-75% weight). Past papers matter enormously — download NET past papers from CampusAxis
- UET Lahore strategy: Balance FSc prep and ECAT — FSc is 50% of your merit
- Multiple applications: Apply to 3-5 universities simultaneously — different formulas may favor your profile
- Use the merit calculator: Know your standing before the admission deadline — calculate now
