If you cleared NEET UG 2026 and registered for central counselling, the choice-filling stage for Round 1 is now live, and this is arguably the most consequential step in the entire admission process. The Medical Counselling Committee (MCC), which conducts central counselling for all-India quota and central institute seats, opened the choice-filling window on August 6, 2026, giving registered candidates until August 13 to lock in their preferred course-college combinations. Getting this list right — in the correct order — directly decides which college you get allotted, so it deserves careful attention rather than a rushed last-day submission. This piece walks through what choice filling means, how the seat matrix fits in, and practical tips for ordering your choices.
Candidates registered for NEET UG Counselling 2026 must enter and lock their course-college preferences at mcc.nic.in by August 13, and the order in which choices are listed — not just which colleges are chosen — determines the Round 1 seat allotment.
What exactly is happening right now
MCC has opened the online choice-filling facility for Round 1 of NEET UG Counselling 2026. This is separate from registration — candidates must first register and fill the application form, and only then can they access the choice-filling link to list colleges and courses.
The window to enter, save, and finally lock these choices closes on August 13, 2026. Locking is the final step; once locked, choices generally cannot be edited for that round, so candidates should treat the last date as a hard deadline and finish well before it.
Why choice filling matters more than most candidates realise
Many aspirants assume that simply registering guarantees a fair shot at their preferred college. In reality, MCC's algorithm allots seats strictly based on the order of choices submitted, matched against a candidate's NEET rank, category, and the number of seats available. A college you badly want but forget to add to your list simply cannot be allotted to you, no matter how good your rank is.
Equally, listing colleges in a careless or random order can result in an allotment you did not actually want, because the system stops at the first available choice on your list that matches your rank and eligibility — it does not wait to see if a 'better' choice further down might have worked out too.
The seat matrix — check it before you finalise anything
MCC releases a seat matrix for each round listing available seats by college, course (MBBS or BDS), and category. This document is expected to be published shortly on the official website and is essential reading before choice locking, since it tells you which colleges genuinely have seats to offer in Round 1.
The seat matrix is revised after every round based on how many seats got filled and vacated, so the picture for Round 2 onward will look different. For Round 1, candidates should cross-check every college on their wishlist against the current matrix rather than relying on last year's data or hearsay.
Step-by-step: how to complete choice filling
The process is straightforward once you know the sequence, but each step should be done carefully since mistakes here are hard to reverse after locking.
- Visit the official MCC counselling website and log in with your NEET UG roll number and password
- Complete registration and the counselling application form if not already done
- Open the choice-filling link and browse available courses and colleges using the seat matrix as reference
- Add your preferred course-college combinations in strict order of preference — most wanted first
- Save the choices as you go; review the full list carefully before final submission
- Lock the choices once you are certain of the order
- Save and submit — after locking, changes are typically not permitted for that round
Practical tips for ordering your list
A common mistake is listing only 'dream' colleges and ignoring realistic backups, which can leave a candidate unallotted in Round 1 and forced to wait for later rounds. Equally, listing too few choices reduces your chances unnecessarily.
Aspirants should rank choices by genuine preference, not just perceived prestige — factor in location, fee structure, hostel and clinical exposure, and your own rank relative to previous years' closing ranks for that college and category. It also helps to include a realistic mix: a few ambitious choices, several matched to your expected rank range, and some safer options lower down the list.

See My CollegesFrequently asked questions
By when do I need to lock my Round 1 choices?
Choices must be entered, saved and locked at mcc.nic.in by August 13, 2026. After locking, the round-specific list generally cannot be changed.
Can I edit my choices after locking them?
No. Locking is meant to be the final step for that round, so candidates should review their entire preference order carefully before locking.
What is the seat matrix and why should I check it before filling choices?
The seat matrix lists, college-wise and category-wise, how many seats are actually available for allotment in that round. Checking it prevents you from wasting choices on colleges that have no seats left in your category for Round 1.
Does the order in which I list colleges actually affect my allotment?
Yes, significantly. MCC allots the first eligible choice on your list that your rank qualifies for — it does not compare all your choices to find the 'best' one. So higher-preferred colleges should always be listed above lower-preferred ones.
What if I don't get any college in Round 1?
Unallotted candidates typically remain in contention for subsequent rounds, when the seat matrix is revised based on vacated seats. It is still worth entering a full, realistic list in Round 1 to maximise your chances early.
Is this choice-filling window only for MBBS, or BDS too?
Both MBBS and BDS seats under the all-India quota and central institutes are covered through this same MCC counselling and choice-filling process.
With the choice-filling window live and the August 13 lock-in approaching fast, aspirants should download the latest seat matrix as soon as it is published, cross-check it against their rank, and build a realistic, well-ordered preference list rather than waiting until the final day. MedAdmit will continue tracking the Round 1 schedule, seat matrix updates, and subsequent rounds as MCC releases them.
