In short: NEET UG 2026 was cancelled after a paper leak was confirmed, affecting approximately 22 to 23 lakh registered students — the largest exam cancellation in Indian history. The leak originated through physical networks in Bihar and Rajasthan, not through Telegram. NTA was restructured: all 47 officials involved in NEET UG were removed and a new task force was formed (Money Control). For 2027, NEET moves to a computer-based test (CBT) format spread over 5 to 6 days at approximately 1,000 centres (Indian Express). This post covers the complete timeline, the government's response, and every confirmed change for NEET 2027.
Last updated: October 29, 2026.
The Scale of What Happened
To understand why NEET 2027 is being restructured so fundamentally, you need to understand the scale of the 2026 cancellation:
| Metric | Figure |
|---|---|
| Students registered for NEET UG 2026 | Approximately 22 to 23 lakh |
| Exam cancelled before it could be held | Yes — cancelled before the exam date |
| States where leak network was active | Bihar, Rajasthan (confirmed), others under investigation |
| NTA officials removed | 47 |
| New task force formed | Yes — high-level committee with external experts |
| Fake "re-exam leak" videos on Telegram | Multiple — all confirmed fake by NTA and PIB Fact Check |
This was not a repeat of NEET 2024, where the exam was held and grace marks were given to 1,563 students. In 2026, the exam was cancelled before it happened — a first in NEET's history.
The Timeline: What Happened and When
Before the Exam
| Period | Event |
|---|---|
| Early 2026 | NEET UG 2026 registration opens. Approximately 22 to 23 lakh students register across India. |
| Weeks before exam | Intelligence inputs about a possible paper leak reach authorities in multiple states. |
| Days before exam | Specific question papers begin circulating in certain districts of Bihar and Rajasthan through physical networks — middlemen, coaching institute owners and exam centre staff. |
| Night before exam | Multiple Telegram channels post what they claim are the question papers. NTA issues a denial. |
The Cancellation Decision
| Event | Detail |
|---|---|
| Exam cancelled | The government announces the decision citing credible evidence of a paper leak. The exam is cancelled before it can be held. |
| Immediate aftermath | 22 to 23 lakh students who had prepared for years face an uncertain future. Coaching institutes, parents and students demand accountability. |
| Fake re-exam videos | Within 48 hours, multiple Telegram channels post videos claiming to show the "re-exam paper." |
| NTA denial | NTA issues a categorical denial: "NTA categorically denies any paper leak for the re-examination. Legal action will be taken against those spreading misinformation" (The Statesman). |
| PIB Fact Check | PIB Fact Check independently flags the Telegram videos as false. |
The Investigation
| Event | Detail |
|---|---|
| CBI investigation | CBI takes over the investigation. Multiple arrests are made across Bihar, Rajasthan and Gujarat. |
| Leak origin confirmed | The leak originated from physical networks — printing press employees and exam centre staff — not from NTA's digital systems. |
| NTA restructuring | All 47 NTA officials involved in NEET UG are removed. A high-level task force is formed to review NTA's processes (Money Control). |
| New leadership | NTA gets new leadership with a mandate to overhaul exam security. |
| Public Examinations Act invoked | Prosecutions filed under the Public Examinations (Prevention of Unfair Means) Act, 2024. |
The Policy Response
| Decision | Detail |
|---|---|
| NEET 2027 format | Moves to computer-based test (CBT) format |
| Duration | 5 to 6 days at approximately 1,000 centres (Indian Express) |
| Multi-session | Different question sets across sessions with normalisation |
| Centre expansion | From approximately 500 centres to approximately 1,000 |
| Security overhaul | Biometric verification, AI-monitored CCTV, no printed papers |
Why the Leak Happened: What the Investigation Found
The NEET 2026 leak was not a digital hack. It was a physical network. Understanding this is important because it explains why CBT addresses the root cause:
The supply chain of a printed paper:
- Question papers are set by subject experts and stored in encrypted form
- Papers are sent to approved printing presses under security protocols
- Printed papers are sealed and transported to exam centres
- Papers are opened at the exam centre on exam day
The leak happened at step 2 or 3: individuals with physical access to the printing or transport process photographed or copied papers before they were sealed. The papers were then distributed through a network of middlemen — primarily in Bihar and Rajasthan — to coaching institutes and individual students who paid large sums (reportedly ₹30 to ₹50 lakh per paper in some cases).
Why Telegram was not the source:
The papers that appeared on Telegram were mostly fake — previous year papers or fabricated documents. The genuine leak happened through physical channels. This is the consistent pattern across every documented exam leak in India.

What Changes for NEET 2027: Every Confirmed Update
Format Change: Pen-and-Paper to CBT
| Aspect | NEET 2026 (cancelled) | NEET 2027 (announced) |
|---|---|---|
| Mode | Pen-and-paper (OMR) | Computer-based test (CBT) |
| Duration | 3 hours 20 minutes | Expected to remain similar |
| Questions | 200 questions (180 to attempt) | Expected to remain similar |

Why CBT Eliminates the Leak Vector
| Old system (printed paper) | New system (CBT) |
|---|---|
| Papers printed weeks in advance | Questions stored encrypted, delivered digitally at exam time |
| Physical transport to 500+ centres | No physical paper to transport |
| Printing press employees have access | No printing press involved |
| One paper for all students on one day | Different question sets across sessions |
| A single leak compromises all students | A leak of one session's paper affects only that session |
Security Changes
| Change | Purpose |
|---|---|
| No printed papers | Eliminates the printing press leak vector entirely |
| Questions delivered digitally at exam time | Cannot be photographed in advance |
| Different question sets across sessions | Reduces the value of any single leak |
| Normalisation across sessions | Ensures fairness when different students get different papers |
| Biometric verification at centres | Prevents impersonation |
| CCTV with AI monitoring | Detects unusual behaviour in real time |
| Dedicated CBT centres | Secure infrastructure, not repurposed school classrooms |
NTA Restructuring
| Change | Detail |
|---|---|
| All 47 NEET UG officials removed | New team with no prior NEET involvement |
| New Director General | Appointed with a mandate for transparency |
| Independent audit | Third-party audit of all NTA processes |
| Grievance portal | Upgraded for faster resolution |
| External oversight | High-level task force with external experts |
What This Means for Your Preparation
The Good News
CBT is structurally harder to leak. There are no printed papers to photograph. Questions are delivered digitally at the time of the exam. Even if someone compromised one session's questions, it would not affect other sessions.
More centres means less travel stress. With approximately 1,000 centres, you are more likely to get a centre close to home. In 2026, many students had to travel to distant cities for their exam centre.
Normalisation is a well-understood process. JEE Main has used normalisation across sessions for years. The process is transparent and the formula is published. It is not a black box.
The New Challenges
CBT practice is essential. If you have only practised on paper, you need to get comfortable with a computer-based interface. Typing answers, using the on-screen calculator, navigating between questions on a screen, and managing the virtual scratchpad are all different from paper.
Multi-session anxiety is real. Students worry about whether different sessions have different difficulty levels. Normalisation addresses this, but understanding how it works reduces anxiety. For how the CBT format works, see our NEET 2027 CBT Mode Complete Guide.
Slot booking matters. With a multi-day exam, popular cities and dates fill up fast. Book your slot as soon as registration opens.

The Fake Telegram Leak: What Actually Happened
After the cancellation, multiple Telegram channels posted videos and images claiming to show the "re-exam paper." Here is what was confirmed:
| Claim | Reality |
|---|---|
| "Re-exam paper leaked on Telegram" | NTA denied this. PIB Fact Check flagged it as false. |
| "Pay ₹500 for the answer key" | Classic scam. No one with a real paper sells it for ₹500. |
| "10,000 students already downloaded" | Fabricated social proof. |
| "Paper will be deleted in 2 hours" | Manufactured urgency to prevent critical thinking. |
NTA's official statement: "NTA categorically denies any paper leak for the re-examination. Legal action will be taken against those spreading misinformation" (The Statesman).
Frequently Asked Questions
Was NEET 2026 actually cancelled or just postponed?
NEET UG 2026 was cancelled. Students had to wait for NEET 2027, which is being restructured as a CBT exam. There was no re-exam for NEET 2026.
Will NEET 2027 have the same syllabus?
The syllabus is expected to remain based on Class 11 and 12 NCERT Biology, Physics and Chemistry. No official change to the syllabus has been announced. Check nta.ac.in for the official notification when it is released.
How does normalisation work in a multi-session exam?
Normalisation adjusts scores to account for differences in difficulty between sessions. The method NTA uses for JEE Main — and is expected to use for NEET 2027 — is based on the percentile of the student's score within their session. A student who scores at the 95th percentile in a harder session gets the same normalised score as a student at the 95th percentile in an easier session. The raw marks are converted to normalised marks, and the normalised marks are used for the merit list.
When will NEET 2027 registration open?
Registration is expected around February 2027. Watch nta.ac.in for the official notification. Do not rely on third-party websites for registration dates.
Is CBT harder than pen-and-paper?
The questions are the same difficulty. The interface is different. Students who practise on CBT platforms before the exam consistently report less anxiety on exam day. The main adjustments are: reading long Biology passages on a screen, using the on-screen calculator for Physics and Chemistry numericals, and managing time without the ability to physically flip through pages.
Where can I practise for CBT NEET 2027?
NTA's official mock test platform at nta.ac.in. SATHEE (sathee.prutor.ai), developed by IIT Kanpur with Ministry of Education support, offers free CBT practice for NEET. Both are free.
What happened to the students who were registered for NEET 2026?
Students registered for NEET 2026 will need to register again for NEET 2027. Their 2026 registration does not carry over. Check nta.ac.in for the official notification on eligibility and registration.
