In a development that has shaken over 22 lakh medical aspirants across India, the National Testing Agency (NTA) officially cancelled the NEET UG 2026 examination conducted on May 3, 2026. The decision came after a "guess paper" — allegedly circulating on WhatsApp — turned out to match a staggering number of actual exam questions in Biology and Chemistry. The Government of India has since ordered a Central Bureau of Investigation (CBI) probe, and a fresh re-exam date is expected to be announced shortly.

At Sri Chaitanya North, our students and families deserve the clearest, most complete picture of what happened, why it happened, and — most importantly — what you should do right now. We've broken down everything below.

The Full Story: How the Paper Leak Unfolded

The controversy that upended NEET UG 2026 has all the hallmarks of an organised malpractice network — and it started with a single WhatsApp message sent the night before the exam.

It Began with a WhatsApp Message

On the evening of May 2, a medical student studying MBBS in Kerala forwarded 300 "guess paper" questions to his father's phone in Sikar, Rajasthan. The accompanying message: "My friend from Sikar sent these to me. Please give them to the girls in your hostel. These are the questions that will come tomorrow."

The operator of a PG hostel where the father worked distributed those papers to students the next morning — just hours before the exam. It was only after the exam concluded on May 3 that a teacher at a nearby Sikar coaching institute sat down with the papers to check how many questions had actually appeared. What he found was staggering: all 90 Biology questions asked in the exam were found within a 200-question Biology guess paper, and 45 out of 45 Chemistry questions also appeared to match.

The Guess Paper: Origins and Scale

According to investigators, the "guess paper" being examined was a handwritten set of approximately 410 questions. Of these, nearly 120 questions are alleged to have directly appeared in Biology and Chemistry sections of the actual NEET UG 2026 paper. The paper had reportedly been circulating among students at least 42 hours before the exam began, shared widely via WhatsApp groups.

The Rajasthan Police Special Operations Group (SOG) found similar videos and copies of test-series papers also circulating from a coaching academy in Latur, Maharashtra, raising concerns about the geographic reach of the breach.

The Likely Source: A Printing Press in Jaipur

Initial findings by investigators suggest the NTA's own digital system may not have been compromised. Instead, the leak is believed to have originated either at the printing press in Jaipur where question papers were produced, or from someone involved in setting the paper. This is a common vulnerability in large-scale Indian competitive exams — the physical printing and transportation chain — despite NTA's stated use of GPS-tracked vehicles and AI-based CCTV at exam centres.

A Timeline of Key Events

Who Is Being Investigated & What Has Been Found

The investigation involves multiple law enforcement wings and is expanding rapidly.

NEET's Security Measures — And Why They Weren't Enough

NTA has consistently claimed that NEET UG 2026 was its most secure exam ever. In its official statement, the agency cited: GPS-tracked question paper transportation vehicles, AI-assisted CCTV surveillance from a central control room, biometric verification of every candidate, 5G jammers at all centres, and unique watermark identifiers on question papers.

And yet, the leak happened. Investigators believe it most likely occurred at the physical printing and handling stage — not through digital channels. This highlights a long-standing blind spot: even the most advanced exam-day security cannot protect against a breach in the supply chain before papers reach the centre.

This is not the first time. NEET UG 2024 was also engulfed in controversy over paper leak allegations, and the matter had reached the Supreme Court of India. Critics argue that structural reforms to the examination and printing process are long overdue.

What Happens Next: The Official Plan

Here is what NTA has officially confirmed as of May 12, 2026:

What You Should Do Right Now: A Student Action Guide

We know this news is deeply unsettling. You've put in months of hard work, and having your exam cancelled through no fault of your own is an incredibly frustrating experience. But here's the silver lining: you now have extra time — use it wisely. The syllabus hasn't changed. Your preparation isn't wasted. The re-exam will come, and the student who uses this window well will come out ahead.

Political & Public Reaction

The cancellation has triggered fierce political debate. Former Rajasthan Chief Minister Ashok Gehlot stated the move points to "large-scale irregularities" and demanded accountability. The Akhil Bharatiya Vidyarthi Parishad (ABVP) has demanded a fair, time-bound investigation and strict action against those responsible. The Indian National Congress attacked the ruling government, with leaders saying "NEET is not an exam anymore."

Medical professionals have also spoken out. Dr. Dhruv Chauhan of the Indian Medical Association Junior Doctors Network noted that the same pattern of allegations arose in NEET 2024 and was dismissed at the time — only for subsequent arrests to prove otherwise.

The NEET 2024 Parallel: Have We Been Here Before?

Uncomfortable as it is, this is not India's first rodeo with NEET controversies. In 2024, mass protests by students and parents led to the matter being taken all the way to the Supreme Court of India. NEET PG 2024 was cancelled just a day before it was scheduled to be held — itself a consequence of leak allegations. In both cases, the initial government response was to dismiss claims as rumours, only for subsequent arrests to confirm the fears.

The recurring nature of these incidents points to systemic vulnerabilities in India's exam infrastructure. Experts and educationists have called for root-and-branch reforms: digitising paper-setting and printing workflows, reducing the number of people with access to question papers before exam day, and implementing Ministry of Education oversight at every stage.
