The Upgrading Process: How It Actually Works
The MDCAT admission process across Pakistan—particularly under the University of Health Sciences (UHS) in Punjab—operates through multiple merit lists. After the MDCAT results are announced, the admitting university typically publishes three or more rounds of selection lists until all seats are filled[reference:0][reference:1].
Here's the sequence:
- Provisional Merit List: Allows students to review their data and request corrections[reference:2].
- First Selection List: Admissions offered to top-merit students[reference:3].
- Second Selection List: Fills remaining vacant seats[reference:4].
- Third and Final Selection List: Concludes open merit admissions[reference:5].
However, the process doesn't always stop at three lists. In some cycles, UHS has issued as many as 16 lists for MBBS in public sector medical colleges[reference:6]. The number of lists depends entirely on how many seats remain vacant after each round.
Candidates who appear in a selection list must pay the prescribed fee within three days or lose their seat[reference:7][reference:8]. Those who join their allotted college are then eligible for upgradation in subsequent lists—provided they haven't exercised the "Freeze" option[reference:9].
For the second or subsequent list, no separate form needs to be filled. The choices of colleges you submitted during your initial application remain active throughout the process[reference:10]. Your original preference order determines which upgrades you're considered for.
Freeze vs. Float: The Decision That Changes Everything
After the first admission round, the university typically offers all admitted candidates a "Freeze" option[reference:11]. This is the single most consequential decision you'll make in the merit list process.
FREEZE: The Safe Bet
- You lock in your current seat. You are no longer considered for any upgrades[reference:12].
- You cannot withdraw your admission after freezing[reference:13].
- Certainty: You know exactly where you're going. No anxiety about future lists.
- Ideal for: Candidates who are satisfied with their allotted college and don't want to risk losing it.
FLOAT: The Gamble
- You keep your current seat provisionally while remaining in the upgrade pool.
- You may be upgraded to a higher-preference college in subsequent lists[reference:14].
- Risk: If you don't get upgraded, you keep your current seat—but you've delayed hostel booking, book purchases, and other logistics.
- Ideal for: Candidates who are genuinely unhappy with their current allotment and have a realistic chance of upgrade.
Some systems offer a "Reject & Upgrade" option, where you reject your current seat to be considered for a higher preference in the next round[reference:15]. This is extremely risky. If you reject your seat and don't get upgraded, you lose everything. Only consider this if your aggregate is significantly above the closing merit of your target college.
The Mathematical Drop-Off: Why Merit Lists Barely Move
Here's the statistical reality that most students don't understand: merit lists typically drop by only 0.01% to 0.05% between the 2nd and 3rd iterations. In some cycles, the drop is so negligible that it barely registers[reference:16].
Consider the 2024 public medical college merit data under UHS[reference:17]:
- King Edward Medical University, Lahore: 96.0591%
- Allama Iqbal Medical College, Lahore: 95.5955%
- Nishtar Medical College, Multan: 95.1409%
- Rawalpindi Medical University: 94.7636%
- D.G. Khan Medical College: 94.3409%
These are final list closing merits. The first list closing merits were even higher. The drop across all lists was fractions of a percentage point. If you're 0.5% below the closing merit of your 3rd choice, you are not going to get upgraded—no matter how many lists are issued.
If your aggregate is more than 0.5% below the closing merit of your target college in the first list, do not expect an upgrade. The merit drop across lists is rarely enough to bridge that gap. The only exception is when a significant number of top-tier candidates decline their seats—which is rare.
The Logistical Nightmare: Moving Hostels and Buying Books Late
Even if you do get upgraded, there's a hidden cost that most students don't consider: the logistical chaos of moving late.
When you float and get upgraded in the 3rd or 4th list, you're often making the switch weeks into the academic calendar. This means:
- Hostel accommodation: The best hostels are already full. You'll be scrambling for whatever is left—often farther from the college, more expensive, or lower quality.
- Textbooks and equipment: Your new college may use different textbooks, have different uniform requirements, or require different equipment. You've already bought everything for your old college.
- Transport and logistics: Moving cities, arranging transport, and settling into a new environment while classes have already started is exhausting—and it distracts from your studies.
- Social integration: By the time you join, your classmates have already formed groups, made friends, and established study circles. You're the "late joiner."
These are real costs that don't appear in any merit formula. For many students, the "prestige" of upgrading to a slightly higher-ranked college is not worth the logistical and social disruption.
Don't let the pursuit of a "better" college blind you to the practical realities. If you're happy with your 4th choice, freeze and move on with your life. The difference in education quality between most public medical colleges is marginal. The real difference is in your own effort and consistency.
Private College Fee Refunds: What Happens If You Upgrade
If you've paid a fee to a private medical college and then get upgraded to a public sector seat, you are legally entitled to a full refund—without any deductions.
Under UHS and PMDC policies, private colleges are legally bound by an affidavit to adhere strictly to fee refund and transfer policies[reference:18]. In cases where candidates upgrade in subsequent selection lists, colleges are obligated to transfer the candidate's full fee to the newly allotted college without any deduction[reference:19][reference:20].
The key details:
- Full refund: The college must refund all fees without deductions[reference:21].
- Timely process: The refund must occur within a week[reference:22][reference:23].
- Legal obligation: If a college fails to comply, its authorization to collect fees directly may be revoked, and legal action will be taken[reference:24].
This protection applies whether you're upgrading from a private to a public college or from one private college to another. The policy ensures that your financial investment is not jeopardized by the upgrading process[reference:25].
Only colleges that have submitted the required affidavit to UHS are authorized to collect fees directly[reference:26]. If a college hasn't submitted the affidavit, UHS collects a token fee (Rs 1 million for open merit seats) to protect candidates' rights[reference:27]. Always verify that your college has submitted the affidavit before paying.
What This Means for You: A Practical Decision Framework
Here's a decision framework to help you choose between Freeze and Float:
- Calculate your exact aggregate. Use the PMDC formula: Matric (10%) + FSc (40%) + MDCAT (50%)[reference:28].
- Compare your aggregate to the closing merit of your higher-preference colleges from the first list (not the final list).
- If you are within 0.05% of the closing merit of your 3rd choice, floating has a small but realistic chance of success.
- If you are more than 0.1% below, the statistical probability of an upgrade is negligible. Freeze and move on.
- Consider the logistical costs. Are you willing to deal with late hostel booking, buying new books, and starting classes late? If not, freeze.
- If you're in a private college and hoping for a public upgrade, your fee is protected. But the merit gap is usually enormous—so be realistic.
The bottom line: Freeze unless you have a very strong statistical reason to float. The peace of mind, logistical simplicity, and ability to start your academic life on time are worth more than the marginal prestige of a slightly higher-ranked college.

Freeze means you lock in your current seat and are no longer considered for upgrades to higher-preference colleges. Float means you keep your current seat provisionally while remaining in the pool for potential upgrades to colleges you ranked higher on your preference list.
Merit drops are typically very small—often just 0.01% to 0.05% between the 2nd and 3rd iterations. In highly competitive years, the drop can be negligible. For example, in 2024, the closing merit for public medical colleges under UHS exceeded 94% even in the final lists[reference:29].
Under UHS and PMDC policies, private colleges are legally obligated to transfer your full fee to the newly allotted college without any deduction. Colleges that have submitted the required affidavit must refund all fees within a week if a candidate is upgraded to another institution[reference:30][reference:31].
UHS typically issues a Provisional Merit List, followed by a First, Second, and Third Selection List[reference:32]. However, in some cycles, UHS has issued as many as 16 lists for MBBS in public sector colleges[reference:33]. The number depends on how many seats remain vacant after each round.
No. For the second or subsequent list, no separate form needs to be filled. The choices of colleges you submitted during your initial application remain active throughout the process[reference:34].
If you are upgraded and do not report to the new college, your admission will be canceled[reference:35]. You are bound to join the upgraded college if you accept the upgrade[reference:36].
