Why aggregate determines Pakistani admissions
University admissions in Pakistan rely on a single aggregate number. Your Matric, Intermediate, and entry test scores are each multiplied by a fixed weight and summed to produce this figure. Your position on the merit list depends entirely on it. Even a 1% difference in aggregate can shift you by hundreds of places on a competitive merit list for programs like MBBS or CS engineering.
Standard formulas by program
| Program | Matric | FSc / Inter | Entry test | Test used |
|---|---|---|---|---|
| MBBS / BDS (PM&DC Regulations 2025) | 10% | 40% | 50% | MDCAT |
| UET Lahore engineering (Fall 2026 prospectus) | 17% | 50% (Part-I) | 33% | ECAT |
| NUST (merit criteria, NET basis) | 10% | 15% (Part-I) | 75% | NET |
| General BS (example only) | 25% | 50% | 25% | NAT / NTS |
| MS / MPhil (example only) | 0% | 50% (bachelor's) | 50% | GAT (NTS) |
The first three rows come from the documents cited below; the last two are example weightings, because universities set their own. Always verify the weights in your target university's current prospectus.
Worked examples: calculating HEC aggregate
MDCAT example. Matric 88%, FSc 85%, MDCAT 160 out of 200 (80%). Aggregate = (88 × 0.10) + (85 × 0.40) + (80 × 0.50) = 8.8 + 34.0 + 40.0 = 82.8%.
ECAT example. Matric 87%, FSc 82%, ECAT 280 out of 400 (70%). Aggregate = (87 × 0.17) + (82 × 0.50) + (70 × 0.33) = 14.79 + 41.0 + 23.1 = 78.89%.
How to calculate HEC aggregate with this calculator
- Select the test type preset from the dropdown.
- Verify the weights shown match your university's published formula. Switch to Custom mode to adjust them if needed.
- Enter your Matric percentage.
- Enter your FSc or Intermediate percentage.
- Enter your test score and the total marks for that test.
- Read your aggregate and compare it against last year's closing merit for the program you want.
How much each component affects the aggregate
| Component | MDCAT weight | ECAT weight | 1% improvement adds |
|---|---|---|---|
| Matric | 10% | 17% | 0.10 to 0.17 pts |
| FSc | 40% | 50% | 0.40 to 0.50 pts |
| Entry test | 50% | 33% | 0.33 to 0.50 pts |
For MDCAT, every 1% improvement in MDCAT score adds 0.5 percentage points to the aggregate, more than any other component. For ECAT, every 1% improvement in FSc adds 0.5 points, making FSc preparation the most efficient use of study time.
When to use the HEC Aggregate Calculator (Pakistan)
Use this page when you are applying to multiple program types and want a single calculator with switchable presets. For MBBS admission specifically, use the dedicated MDCAT Aggregate Calculator which uses the PM&DC weighting and passing percentage. For engineering, use the ECAT Aggregate Calculator. For a general university merit calculation with fully custom weights, use the Merit Calculator.
Common mistakes when calculating HEC aggregate
Entering raw test marks instead of percentage. All three inputs must be percentages. An MDCAT score of 160 out of 200 is 80%, not 160. Enter the raw score and the total marks and the calculator converts automatically.
Using last year's weights for this year. Admission weightings are set per admission cycle and universities occasionally update them. Always use the prospectus from the current admission year rather than resources from previous years.
Applying one university's formula to another. NUST weights its test at 75% while UET weights it at 33%. Using the wrong preset can produce an aggregate that differs from the actual merit by 5 to 10 percentage points.
