For nearly a million aspirants across India, the clock is ticking. The National Testing Agency has officially opened the door—just barely—to fix mistakes in JEE Main 2026 Session 1 applications. The correction window? Just two days: December 1 to December 2, 2025, until 11:50 PM IST. Miss it, and your form locks in forever—even if your name’s misspelled or you picked the wrong exam city. Registration closes November 27, 2025, and if you haven’t applied yet, you’re already out of luck.
What You Can and Can’t Change
Here’s the thing: the correction window isn’t a full do-over. You can fix your name, category (General, SC, ST, OBC), exam city preference, and qualification details—like your 12th-grade board or year of passing. But if you entered the wrong mobile number? Too bad. Email ID? Locked. Photograph? No changes. Emergency contact? Forget it. The National Testing Agency made this crystal clear in a November 23 update. These details are tied to your identity verification system, and altering them after submission could trigger fraud flags. It’s not about bureaucracy—it’s about security.
Why This Window Matters More Than You Think
One typo. One misplaced digit. One wrong category selection. Sounds small? It’s not. Last year, over 1,200 candidates in Uttar Pradesh and Bihar had to file affidavits after their admit cards showed the wrong category, delaying their counseling. Others got their exam center in a city they couldn’t reach due to family emergencies. The National Testing Agency doesn’t allow changes after the correction window closes—not even for medical emergencies. The Vedantu Innovations Private Limited team warns: "If your photograph is blurry or your signature is smudged, you won’t get a replacement. The admit card is generated directly from your application data." That means if you uploaded a low-res image in a rush at 11:45 PM on November 26, you’re stuck with it.
Registration Timeline: A Narrow Window
The application process began on October 31, 2025, and ends November 27, 2025. That’s just 28 days for over a million students to fill forms, upload documents, pay fees, and double-check everything. ALLEN Career Institute, which coaches over 300,000 JEE aspirants annually, says traffic spikes on the last three days—servers crash, payment gateways glitch, and uploads fail. Many students don’t realize they need to log back in after payment to confirm submission. "I thought I was done," said 17-year-old Arjun Mehta from Jaipur, who only found out his application wasn’t confirmed until December 1. He missed the correction window. "Now I’m hoping my name is spelled right on the admit card."
Session 2: Another Shot, But Still No Second Chances
Good news: you can take both sessions. Session 1 is in January 2026. Session 2? April 2026. And yes, there’s a correction window for Session 2—but only if you apply for it. The ALLEN Career Institute estimates it’ll open in the last week of January 2026. Vedantu Innovations Private Limited says early February. Either way, it’s a separate process. You can’t use Session 1’s window to fix Session 2’s form. And if you didn’t apply for Session 2? You can’t add it later. You only get one shot at each session’s application.
Who’s Affected—and Who’s Not
This isn’t just about top scorers. It’s about every student aiming for an NIT, IIIT, or GFTI. These institutes use JEE Main scores for 70% of their admissions. A single point can shift your rank by thousands. If your category is wrongly listed as General instead of OBC, you could lose eligibility for reserved seats. If your 12th-grade board is listed as CBSE when it’s actually ICSE, verification fails. And if your photo doesn’t match your ID? You might be barred from the exam hall. The National Testing Agency doesn’t send reminders. No emails. No SMS. You’re on your own.
What’s Next? The Real Deadline Is Already Past
November 27, 2025, is the real deadline—not December 2. If you haven’t applied by then, you can’t correct anything. Even if you apply on November 26, you still have to wait until December 1 to make changes. That’s a 35-day gap where mistakes fester. Experts recommend submitting your application by November 15—giving yourself two full weeks to review, print a copy, and triple-check every field. "I used to tell students to wait," says Priya Sharma, a JEE mentor in Kota. "Now I tell them: submit early. Sleep well. Then come back and fix what’s wrong."
Background: Why JEE Main Has This Two-Day Window
The correction window was introduced in 2021 after widespread complaints about application errors. In 2020, over 8,000 candidates had to file RTI requests just to get their names corrected on scorecards. The National Testing Agency responded by creating this narrow, high-stakes window. It’s not designed for convenience—it’s designed to prevent chaos. Imagine 1.2 million forms being processed, then suddenly needing to re-print 200,000 admit cards because someone changed their city. That’s why the window is so short. And why it’s so critical.
Frequently Asked Questions
Can I change my photograph or email ID during the JEE Main 2026 correction window?
No. The National Testing Agency explicitly prohibits changes to photograph, email ID, mobile number, address, and emergency contact details during the correction window. These are linked to your identity verification and cannot be altered after initial submission. Any mismatch may lead to disqualification at the exam center.
What happens if I miss the December 1–2, 2025 correction window?
Your application details become final. Any errors—whether in name, category, or exam city—will appear on your admit card and scorecard. You won’t be able to request changes later, even with documentation. Many students have been barred from counseling because their category or board details were incorrect. There is no appeal process.
Is the JEE Main 2026 Session 2 correction window the same as Session 1’s?
No. The Session 2 correction window is separate and expected in late January or early February 2026, according to ALLEN Career Institute and Vedantu Innovations Private Limited. You must apply for Session 2 separately, and the correction window only applies to Session 2 applications. You cannot use Session 1’s window to fix Session 2 errors.
Do I need to pay again to make corrections?
No. The correction window is free for all registered candidates. You don’t pay extra to edit your name, category, or exam city. However, if you need to change your exam category (e.g., from General to EWS), you may need to upload supporting documents. Payment is only required during initial registration.
Can I apply for JEE Main 2026 after November 27, 2025?
No. The National Testing Agency has confirmed the registration deadline is firm: November 27, 2025. No extensions, no late fees, no exceptions—even for medical emergencies. If you haven’t applied by then, you’ll have to wait until JEE Main 2027.
How do I know if my application was successfully submitted?
After payment, you must click "Submit Application" on the portal. You’ll receive a confirmation page with a unique application number. Download and print it. If you don’t see this page, your application wasn’t submitted—even if you paid. Many students assume payment equals submission. It doesn’t. Always verify your status on the NTA portal before November 27.
