Tamil Nadu NEET UG Round 2 Seat Matrix 2026: Vacancy List & Choice Filling Deadline

The Directorate of Medical Education and Research (DMER) in Tamil Nadu has published the Round 2 seat matrix for NEET UG 2026, showing all available MBBS and BDS vacancies across government, government-aided, and private medical and dental colleges in the state. This is a critical document for any candidate who registered for Round 2 counselling, as it forms the basis for your college and course selection. The choice-filling window is now open, but you have only until September 13 at 2:00 PM to lock your preferences—missing this deadline means you cannot participate in Round 2 allotment. Understanding what seats are available, which colleges are included, and how to strategically fill your choices can be the difference between securing a government MBBS seat and moving to the mop-up round.

What Is the Round 2 Seat Matrix and Why Does It Matter?

The seat matrix is a detailed list of all vacant MBBS and BDS positions available for Round 2 allotment in Tamil Nadu. These vacancies arise from two sources: seats that remained unfilled after Round 1 counselling concluded on September 5, 2026, and positions surrendered by candidates who chose to withdraw from the admission process. The matrix is organised by college, course, category, and quota, allowing you to see exactly which seats are open and which institutions have capacity.

For a NEET aspirant, the seat matrix is your roadmap. It tells you which colleges have seats in your category (general, OBC, SC, ST), how many positions are available at each institution, and whether you should include that college in your preference list. Without this information, you would be filling choices blindly. Round 2 is often the last chance to secure a government medical or dental seat in Tamil Nadu, as seats not filled here move to mop-up and stray vacancy rounds, which typically have fewer options and tighter timelines.

Which Seats Are Included in Round 2?

Round 2 covers 85 percent of state quota seats in government medical and dental colleges, as well as 100 percent of seats in private medical and dental colleges. This means all government-aided and self-financing institutions in Tamil Nadu are part of this round. However, deemed universities and All India Quota (AIQ) seats are not included in state counselling and follow a separate admission process.

To give you context, Round 1 had 8,063 MBBS seats and 1,859 BDS seats available. The Round 2 pool is smaller because many candidates have already been allotted and have reported to their colleges. The exact number of vacancies in Round 2 depends on how many Round 1 allottees actually joined their colleges by the September 5 deadline. This is why the seat matrix is released after Round 1 reporting closes—it reflects the true vacancy position.

• Government medical and dental colleges (85% state quota)
• Government-aided medical and dental colleges
• Self-financing private medical and dental colleges
• Excludes: deemed universities and All India Quota seats

How to Access and Download the Seat Matrix

The seat matrix is available as a downloadable PDF on the official DMER portal at tnmedicalselection.net. The process is straightforward: visit the portal, look for the Notifications or View All section on the homepage, find the notification titled 'NEET UG 2026 Round 2 Seat Matrix,' and download the MBBS and BDS PDF files. You will see vacancies listed college by college and category by category, making it easy to identify which institutions have seats in your eligibility bracket.

Download both the MBBS and BDS matrices even if you are only interested in one course, because the information helps you understand the overall competition and vacancy landscape. Save these PDFs to your device so you can refer to them while filling your choices. Many candidates print the matrix or keep it open on a second screen while logging into the counselling portal to fill their preferences.

Critical Dates: Choice Filling and Allotment Timeline

Round 2 counselling operates on a compressed 10-working-day schedule, so every date is non-negotiable. Registration and fee payment closed on September 8 at 5:00 PM. The seat matrix was released on September 9. Choice filling is now open from September 9 at 2:00 PM and closes on September 13 at 2:00 PM—this is your only window to add and lock your college preferences. After 2:00 PM on September 13, the system will not accept any changes, so plan your choices carefully and lock them well before the deadline.

Seat processing and allotment happen on September 14, and the allotment result will be published on September 15. If you are allotted a seat, you must report to your college by September 18 to confirm your admission. Missing this reporting deadline can result in your seat being cancelled and offered to the next candidate. The entire process moves quickly, so mark these dates on your calendar and set reminders.

• Registration and fee payment: September 7–8, 2026 (5:00 PM) — CLOSED
• Seat matrix release: September 9, 2026
• Choice filling and locking: September 9 (2:00 PM) to September 13 (2:00 PM)
• Seat processing and allotment: September 14, 2026
• Allotment result publication: September 15, 2026
• Last date to join allotted college: September 18, 2026

How to Fill and Lock Your Choices Strategically

Only candidates who completed Round 2 registration by September 8 can access the choice-filling portal. Log in using your registered credentials on the counselling website. Once inside, you will see a list where you can add colleges and courses in order of preference. The order matters: the system processes your choices from top to bottom, so place your most preferred college first, your second choice second, and so on.

Your strategy should be based on three factors: your NEET UG 2026 rank, your category (general, OBC, SC, ST), and the vacancy data in the seat matrix. Identify colleges where your rank is likely to secure a seat, then arrange them in genuine order of preference. Do not add colleges you would not join, as this wastes your choices. Review your locked list carefully before the 2:00 PM deadline on September 13—once locked, no changes are allowed. If you make a mistake, you cannot edit after locking, so take your time and double-check.

• Log in with your registered credentials
• Add colleges and courses in order of genuine preference
• Base your list on your rank, category, and the vacancy matrix
• Place your most preferred college first
• Review the locked list carefully—no changes allowed after locking
• Lock your choices before 2:00 PM on September 13

Why Round 2 Is Often Your Last Chance for a Government Seat

Many NEET aspirants view Round 2 as their final opportunity to secure a government MBBS or BDS seat in Tamil Nadu. If you do not get allotted in Round 2, your next options are the mop-up round and stray vacancy round, which typically have far fewer seats and are often filled within hours. Additionally, mop-up rounds sometimes have stricter eligibility criteria or shorter reporting timelines, making them riskier.

This is why your choice-filling strategy in Round 2 is so important. You need to balance ambition (aiming for your dream college) with realism (ensuring you have a reasonable chance of getting allotted). If your rank is borderline for a particular college, include it but also add safer options below it. The allotment algorithm will try to place you in the highest-ranked college on your list where you are eligible, so a well-planned preference list maximises your chances of securing a seat.

What Happens After Round 2 Allotment?

On September 15, the allotment result will be published on tnmedicalselection.net. Log in and check whether you have been allotted a seat. If you are allotted, note the college name, course, and seat category. You must then report to that college by September 18 with all required documents (admit card, mark sheet, category certificate if applicable, and other documents as specified by the college). Reporting confirms your admission; without it, your seat is cancelled.

If you are not allotted in Round 2, watch the portal for announcements about the mop-up round. Mop-up rounds typically have a shorter choice-filling window and fewer seats, so be prepared to act quickly. Some candidates also choose to accept a private college seat if they have been allotted one, rather than wait for mop-up. Discuss this decision with your parents and consider factors like fees, location, and college reputation.

• Check allotment result on September 15
• If allotted, report to college by September 18 with required documents
• Reporting confirms your admission
• If not allotted, watch for mop-up round announcements
• Consider private college options if allotted

Common Mistakes to Avoid During Choice Filling

One of the most common mistakes is filling too many choices without a clear strategy. While you can add multiple colleges, each choice should be deliberate. Adding colleges you would never join wastes your chances and can lead to an unwanted allotment. Another mistake is not checking the seat matrix carefully—some candidates miss that a college has no vacancy in their category and waste a choice on it.

A third mistake is locking choices too late. Many candidates wait until the last hour to lock, and technical glitches or internet issues can prevent them from submitting in time. Lock your choices at least 30 minutes before the 2:00 PM deadline on September 13. Finally, do not assume you will get into a college just because your rank seems high enough—cutoffs vary by category and quota, so always cross-check the seat matrix and be conservative in your estimates.

• Do not add colleges you would not join
• Check the seat matrix carefully for your category
• Lock choices well before the deadline, not at the last minute
• Do not assume you will get a seat based on rank alone
• Verify vacancy data for your specific category and quota
