If you've spent the last few days rearranging your college preference list for NEET UG Counselling 2026, tomorrow is when things get a bit more final. The Medical Counselling Committee's Round 1 choice locking phase opens on August 12, and once that clock starts ticking, the room for second-guessing your list starts shrinking fast.

So What Actually Changes Tomorrow?

Right now, you're still in the choice filling stage, adding colleges, reordering your list, removing ones you've reconsidered. That freedom doesn't disappear overnight, but from 4 PM on August 12, MCC opens the dedicated choice locking window, which runs until 11 AM on August 13. This overlaps with the tail end of the choice filling window itself, so you technically still have a small stretch of time to fine-tune your list even after locking opens, but the smart move is to treat tomorrow as your real deadline rather than cutting it close.

  • Choice filling window: August 6/7 to 11 AM, August 13, 2026
  • Choice locking window: 4 PM, August 12 to 11 AM, August 13, 2026
  • Registration and fee payment deadline: 3 PM, August 12, 2026 (payment till 6 PM)
  • Seat allotment processing: August 13 to August 16, 2026
  • Round 1 seat allotment result: August 17, 2026
  • Reporting to allotted institute: August 18 to August 22, 2026

What Locking Your Choices Actually Means

Locking isn't just a formality, it's the point where your preference order stops being a draft and becomes what MCC actually uses for seat allotment. Once you lock, you get a locked choice letter as confirmation, complete with your locking timestamp and other verification details, which is worth downloading and keeping safely.

Here's the part that trips people up every year: if you don't lock manually before the window shuts, MCC doesn't just leave your application incomplete. The system automatically locks whatever list you last saved. That's a safety net in one sense, but it also means an unfinished, poorly ordered, or outdated list could get frozen in exactly that state. It's genuinely worth going back into your account tomorrow and locking deliberately, rather than assuming the system will sort it out for you.

StepWhat to Do Before Locking
Review your listGo through every college and course you've added, in the exact order you want
Check your seat matrixCross-verify availability under your category before finalising priority
Remove uncertain choicesDrop any college you genuinely wouldn't accept if allotted
Lock manuallyDon't leave it to auto-lock; confirm your choices yourself
Download confirmationSave your locked choice letter as proof once locking is done

How to Lock Your Choices

  • Log in to your NEET UG counselling account at mcc.nic.in
  • Open your saved choice list from the Choice Filling section
  • Go through the order one final time and make any last adjustments
  • Click on the option to lock your choices
  • Confirm the action when prompted, since this step generally can't be undone once completed
  • Use the 'Print Locked Choice(s)' option to download your locked choice letter for your records

One More Thing Worth Noting

MCC has also reopened its candidate withdrawal (CW) portal and released an additional merit list for Puducherry domicile candidates in the past couple of days, so if either of those applies to you, it's worth checking the official notices section directly rather than assuming your situation is covered by the general schedule alone. Counselling notices tend to come out with very little warning, and MCC has already shown this cycle that dates can shift, so a quick daily check of the portal genuinely pays off.

Once locking closes tomorrow morning, there's no more editing, no more reordering, whatever's locked is what goes into seat allotment. So between now and then, the priority is simple: make sure your list actually reflects colleges you'd be genuinely willing to join, in the order you'd actually want them.

This is a developing counselling cycle, and any further changes to the schedule would come directly from MCC. Keep checking mcc.nic.in through the day tomorrow rather than relying on secondhand updates.
