Engineering university admission in Punjab and several other provinces uses ECAT as one component of a weighted aggregate — not as a standalone cutoff. Here's the general structure.
Typical Weightage Structure
A commonly referenced formula weights Matric around 17%, FSc (Pre- Engineering) around 50%, and ECAT around 33% — but this varies by university and year, so confirm the exact current formula with your target university's admission office or prospectus.
A Worked Example
(Matric% × 0.17) + (FSc% × 0.50) + (ECAT% × 0.33) = Aggregate
With 88% Matric, 82% FSc, and 70% ECAT: (88×0.17) + (82×0.50) + (70×0.33) = 14.96 + 41 + 23.1 = 79.06%.
FSc Carries the Most Weight Here
Unlike MDCAT-based formulas where the entry test dominates, ECAT-based formulas often weight FSc most heavily — meaning your Pre-Engineering percentage typically has the largest single impact on your final aggregate.
Conclusion
Formulas differ between universities (NUST, UET, and others each run their own admission process with different weightages), so calculate separately for each one you're applying to. Our Aggregate Calculator supports fully custom weightages for exactly this.
