JEE Main 2027: Know These 4 Big Changes Before Filling the Form, or Risk Rejection!

How to Fill the JEE Main 2027 Form: A Step-by-Step Guide

The Session 1 form usually stays open for 25–30 days. To avoid mistakes made in a hurry, keep your documents ready in advance.

Know these 4 big changes before filling the form

• Registration has already started. The form was expected to open at the end of October, but NTA began Session 1 registration on 24 October 2026.
• The last date is 22 November 2026. Submit the form and complete the fee payment before then.
• Session 1 exam dates have changed. The earlier calendar had 22–24 and 28–30 January. The exam will now be held on 20–24 and 28 January 2027.
• The Session 2 schedule is out. Registration will run from 5 January to 3 February 2027, and the exam will be held on 2 to 7 April 2027.

Document checklist

• Your name and date of birth should be identical on your Aadhaar card and Class 10 marksheet. Fill the form exactly as per the Class 10 marksheet.
• Keep the photo on your Aadhaar card updated, because the live photo is matched with it.
• If you don't have an EWS/OBC/SC/ST certificate, apply for it now.
• If you live in a rented house and want an exam centre in that city, get a rent agreement made on stamp paper.

Online application: the full process

1. New registration. Open "Register yourself" on the NTA website and choose New Registration.
2. Basic details. Fill in your name, parents' names, date of birth and gender as per your marksheet.
3. Address. Present address is where you live now; permanent address is your home. Your exam city choice depends on these, so if you want a centre like Kota, enter the present address there.
4. Contact and password. Give your own or your parents' mobile number and email, not a cyber café's. The password needs one capital letter, one small letter and one special character. After verifying the OTPs on mobile and email, keep the application number you receive safe; you will need it for Session 2.
5. Personal details. Home state is the state where you passed Class 12. For OBC, your community must be on the Central List; those on the State List only are counted as General. If you are PwD, enter your UDID number. Fill in the combined family income of both parents accurately.
6. Identity. Choose from Aadhaar card, DigiLocker, passport or PAN. Aadhaar is the easiest. Enter the APAAR ID if you have one; otherwise it is not mandatory.
7. Paper, city and education. Choose Paper 1 for B.E./B.Tech (also tick B.Arch/B.Planning if you want it). Fill in the full Class 10 details. Class 12 details are asked only from droppers.
8. Photo, upload and fee. Scan the QR code with your phone and take a live photo against a plain background. Upload the photo, signature and Class 10 marksheet. Then submit the form and pay the fee. Without the fee the form stays "Incomplete". If the payment shows pending, wait a day; if it still doesn't change, pay again and the first amount will be refunded.

JEE Main 2027 Expected Cut-off: Work It Out Yourself with the Calculator

The cut-off depends most on two things: the total number of candidates appearing in the exam, and the number of candidates in your category shortlisted for JEE Advanced. About 2.5 lakh students are selected for Advanced every year, whether 9 lakh or 15 lakh appear. So if the number of students rises while the seats stay the same, the cut-off goes up.

Formula

Total candidates: From 2024 to 2026 there was an average annual increase of about 4.27% (roughly 60–63 thousand). At the same pace, about 16.04 lakh candidates could appear in 2027.

General shortlisted: Leaving out 2019 (the year EWS was introduced) and 2022 (Covid), the average of the other four years is about 97,539.

From these, the formula result for 2027 comes to about 93.9. In past years the actual cut-off has usually been 0.1 to 0.3 lower than the formula (93.41 against 93.70 in 2026), so the most likely value is about 93.6.

How far can the cut-off go in your category?

How to Crack JEE Main in 90 Days

About 90 days are left until 20 January. After that, in February–March, you get only about 15 days between boards and Session 2, and about 40 days between Main and Advanced. There is room for fresh preparation now, not later.

Why choose the January attempt?

Marks needed for the 94th percentile in 2026 (out of 300):

To get the same percentile in April you need roughly 11 to 19 more marks, because droppers have given all of February–March to studying.

The 90-day plan: how to start

• First 80 days: Study what you haven't studied and revise what you have. Give each chapter about 2 days: 3–4 hours of one-shot revision, the rest on questions. At this pace 40 chapters get done.
• Last 10 days: At least 2 mocks every day, 9–12 in the morning and 2–5 in the afternoon, so your body gets used to the exam timing. Spend 2–3 hours on analysis after each mock. That is 20 tests in 10 days, about 1500 questions.
• Throughout: Revisit your mock mistakes and the questions you couldn't solve.

High-weightage chapters

The NTA syllabus has about 650 topics, but the questions come from a small part of it. Questions from the 39 shifts of 2024 and 2025 were counted chapter-wise. When compared with the 2026 papers, the top chapters matched about 80%.

Physics (14–16 questions per shift from 13–14 chapters; order approximate):

• KTG + Thermodynamics
• Current Electricity
• Electrostatics
• Ray Optics
• Units and Measurements
• Magnetic Effects of Current
• Rotation
• Fluids
• Kinematics
• Modern Physics

Chemistry (questions across 39 shifts):

• d and f Block (78)
• Coordination Compounds (69)
• Chemical Bonding (61)
• Mole Concept (59)
• Thermodynamics (53)
• Practical Chemistry (44)

Maths:

• 3D Geometry
• Sets, Relations and Functions
• Sequences and Series
• Matrices
• Conic Sections (lower weightage, but rising)

15 Exams to Keep an Eye on Along with JEE

Last time 15.38 lakh students appeared and 18,951 IIT seats were filled, so the selection rate is about 1.2–1.3%. Even adding NITs, IIITs and GFTIs, it is only about 4–5%. The JEE syllabus overlaps with many other exams, so one preparation can give you multiple chances.
