* Campus: UET has multiple campuses (Lahore, Taxila, Peshawar, etc.), each with its own separate merit list. The closing merit will be significantly different between campuses.
* Program: Different engineering disciplines (e.g., Computer Science, Electrical Engineering, Civil Engineering) have vastly different closing merits. Highly competitive programs will have much higher closing merits.
* Year: The closing merit fluctuates from year to year based on the number of applicants, their academic performance, and other factors.
To find the last merit for a specific program at a specific UET campus in a specific year, you'd need to consult the official UET website for that particular year's admission results. There's no central, permanently available database of all past closing merits.
