Tamil Nadu's Directorate of Medical Education has released the official seat vacancy document for Round 3 of NEET-UG counselling 2026, covering both MBBS and BDS programmes across government, self-financed, and private colleges. This matrix shows you exactly which seats remain unfilled after Round 2, broken down by college, course, and quota category. If you are a registered NEET-UG candidate in Tamil Nadu, this data is critical: it tells you where seats are available and helps you make informed choices during the choice-filling window that opens October 1. Your decisions now will directly influence the allotment result announced on October 12.
Download the Round 3 seat matrix from tnmedicalselection.net and use it to identify realistic college and course options before you fill and lock your choices between October 1–9, 2026.

Unlock My College ListWhat Is the Round 3 Seat Matrix and Why Does It Matter?
The seat matrix is an official document that lists every vacant seat available in Round 3 counselling, organised by college, course (MBBS or BDS), and quota category. It is released after Round 2 allotments are finalised, showing you the real supply of seats you can compete for in the next round.
For a NEET-UG aspirant, this matrix is your roadmap. It answers the question: 'Where can I actually get a seat?' Rather than guessing or hoping, you can see the exact number of vacancies at each institution and in each quota (state quota, government school quota, or management quota). This transparency helps you avoid wasting choices on colleges where no seats remain, and instead focus on realistic options that match your rank and preferences.
Understanding Tamil Nadu's Quota Structure in Round 3
Tamil Nadu's counselling operates under three main quota categories: the state quota (92.5% of seats), the government school quota (7.5% of seats reserved for students from government schools), and management quota (seats filled by colleges directly, outside the merit-based counselling process). The seat matrix breaks down vacancies for each of these separately, so you know which quota you are eligible for and where seats exist in your category.
If you studied in a government school, you may be eligible for the 7.5% government school quota, which often has lower competition than the general state quota. The matrix will show you these seats explicitly. Similarly, if you are considering management quota seats (which require direct payment to the college), the matrix will indicate their availability. Understanding which quota applies to you is essential before you begin choice filling.
How to Access and Download the Seat Matrix
The seat matrix is available on the official Tamil Nadu Medical Selection portal at tnmedicalselection.net. To find it, visit the homepage, look for the 'UG Courses' or 'Notifications' tab, and search for the document titled 'Tentative Vacancy Position for MBBS/BDS Courses Round-3' under the current academic year. Click the link to open the PDF in your browser.
Once you have the PDF open, you can view all seat vacancies across colleges and categories. Download it to your device so you can refer to it offline while making your choices. Many candidates print it or keep it open on a second screen while filling their choice list, so they can cross-check availability in real time. This is a smart practice: it prevents you from selecting colleges where no seats remain in your quota.

Choice Filling Window: October 1–9, 2026
The choice-filling window for Round 3 opens on October 1, 2026, at 2 PM and closes on October 9, 2026, at 5 PM. During this nine-day period, you must log into the portal, review the seat matrix, and enter your college and course preferences in order of priority. The system will lock your choices at the deadline; no changes are allowed after 5 PM on October 9.
This is your only opportunity to influence your Round 3 allotment. Use the seat matrix to identify 5–10 realistic options (or as many as the system allows) and rank them carefully. Prioritise colleges where seats are genuinely available in your quota and where your rank is competitive. Do not fill choices for colleges with zero vacancies; those will not result in an allotment. Plan ahead: do not wait until the last day to fill your choices, as portal congestion or technical issues could prevent you from submitting in time.
- Choice filling opens: October 1, 2026, 2 PM
- Choice filling closes: October 9, 2026, 5 PM
- No changes allowed after the deadline

Key Dates and Milestones for Round 3
After you submit your choices on or before October 9, the Tamil Nadu DME will process all applications and declare the provisional allotment result on October 12, 2026. This result will show which college and course you have been allotted based on your rank, choices, and availability. If you are allotted a seat, you will then proceed to document verification and fee payment to confirm your admission.
Mark these dates on your calendar and set reminders. Missing the choice-filling deadline means you will not be considered for Round 3 allotment at all. Similarly, if you are allotted a seat but fail to report for verification or pay fees by the specified date, your allotment may be cancelled and the seat offered to the next candidate on the waiting list.

How to Use the Seat Matrix to Make Smart Choices
Every kind of MBBS/BDS seat, one rank
See the real seats your NEET rank can reach.
The seat matrix is most useful when you combine it with your own NEET rank and category. First, identify which quota you belong to (state, government school, or management). Then, scan the matrix for colleges offering MBBS or BDS (whichever you prefer) with available seats in your quota. Cross-reference these colleges with your rank: if your rank is significantly higher than the typical cutoff for that college in previous rounds, you have a good chance of allotment.
Avoid the common mistake of filling choices based on prestige alone. A prestigious college with zero vacancies in your quota will not help you. Instead, prioritise colleges with confirmed vacancies where your rank is competitive. If you are unsure about your rank's competitiveness, consult your state's previous round cutoff data or speak to a counsellor. The goal is to fill your choice list with colleges where you have a realistic chance of allotment, ranked in order of your preference.
- Identify your quota category (state, government school, or management)
- Find colleges with available seats in your quota
- Cross-check your rank against typical cutoffs for those colleges
- Prioritise realistic options over prestigious but unavailable colleges
- Rank your choices in order of genuine preference
What Happens After Round 3 Allotment?
Once the allotment result is declared on October 12, you will know whether you have been allotted a seat and, if so, at which college and in which course. If you are allotted, you will be required to report for document verification (original certificates, mark sheets, identity proof, etc.) and pay the admission fee within a specified timeframe. Failure to do so will result in cancellation of your allotment.
If you are not allotted in Round 3, you may be eligible for a waiting list or a subsequent round (if the state conducts one). Check the portal regularly for updates. Some candidates also choose to accept a management quota seat at a private college if they are not allotted in the merit-based rounds. Understand all your options before Round 3 closes so you can plan your next steps.
- Allotment result declared: October 12, 2026
- Document verification and fee payment required if allotted
- Failure to report or pay will cancel your allotment
- Check for waiting list or subsequent round opportunities
- Consider management quota options if not allotted in merit rounds
Common Mistakes to Avoid During Choice Filling
One of the most frequent errors is filling choices for colleges with no vacancies in your quota. The seat matrix clearly shows this; if a college has zero seats available, do not waste a choice on it. Another mistake is ranking colleges in reverse order of preference—putting your dream college last and a backup college first. Remember, the system allots based on your rank and the order you rank your choices, so always put your genuine first preference at the top.
A third pitfall is filling too few choices. If you fill only three choices and none of them result in an allotment, you will not be allotted any seat in that round. Fill as many realistic choices as the system allows (typically 10–20). Finally, do not ignore the deadline. Submitting your choices on October 8 or 9 is fine, but waiting until the last hour risks technical glitches or portal overload. Submit early and verify that your choices have been locked successfully.
- Do not fill choices for colleges with zero vacancies
- Rank colleges in order of your genuine preference, not reverse order
- Fill as many realistic choices as allowed
- Submit your choices well before the October 9 deadline
- Verify that your choices have been locked after submission
