JEE Main Chemistry Question Paper: Are you a JEE aspirant and looking for the previous year chemistry question paper? Then you are in right place. JEE Main is the biggest exam for engineering aspirants, and it is conducted twice a year. The JEE Main Chemistry paper is officially released on its official website. In this article, we have provided JEE Mains 2026 exam chemistry preparation material and question papers. Aspirants who are preparing for JEE Mains 2026 can also download the paper from jeemain.nta.nic.in addition to the answer key.
As per JEE Main 2026 information bulletin, if a candidate has passed the Class 12 examination from one state but appeared for improvement from another state, the state code of eligibility will be from where the candidate first passed the qualifying exam and not from where they appeared for improvement.
Those who have passed Class 12 or appearing for the exam from the National Institute of Open Schooling (NIOS) should select the state of eligibility according to the state in which the study centre is located. For Indian nationals passing the Class 12 exam from Nepal or Bhutan, the eligibility will be determined based on a permanent address in India as given in the passport of the candidate.
Overseas Citizens of India (OCI) passing the Class 12 from an institution abroad are eligible for other state quota seats or All India quota seats, but not for home state quota seats in all NITs, IIITs and Other-CFTIs.

Frequently Asked Questions (FAQs)
Candidates can download the JEE Main 2025 question paper from the official NTA website.
Each question is awarded 4 marks for a correct answer, deducted 1 mark for a wrong answer and unanswered questions do not carry any marks.
IIT Roorkee will set the 2026 question paper.
Yes, 96% percentile in JEE Mains is a good score, and you can get into NITs, newer IIITs, along with other reputed institutions.
Yes, you can appear for JEE Mains, as the eligibility allows three consecutive years from your 12th passing year, but no, you cannot appear for JEE Advanced, as the eligibility is limited to the year of passing 12th and the following year. Therefore, if two years have passed since your 12th board exams, you are likely only eligible for JEE Mains.
On Question asked by student community
Hello, Yes, this mismatch will absolutely cause a problem during your JEE Mains 2026 registration, but there is a clear solution.
You must enter your father's name "Girisharadya" (without the 'a') in the main application form, as it appears on your 10th-grade marksheet. The 10th marksheet is the primary, non-changeable document for all NTA applications.
When the system tries to verify this with your Aadhaar, it will detect a mismatch ("Girisharadya" vs. "Girisharadhya") and will show a pop-up warning. NTA has created a process for this: you will be given an option to enter your father's name as per your Aadhaar in a separate field. The system will then capture both spellings, allowing you to complete the registration.
However, since you have time before 2026, the safest and most highly recommended solution is to get your Aadhaar card (and your father's) corrected to match the spelling on your 10th marksheet ("Girisharadya"). This will prevent any confusion or problems later during JoSAA counselling and final document verification.
I hope you found this information helpful and for any study related queries you can ask in careers360 app, Have a great day!
Hello Aspirant,
Jee main's high scoring chapters:
For mathematics : Coordinate Geometry, Calculus (especially Integral Calculus), and Algebra (Complex Numbers, Quadratic Equations, Matrices, Determinants) .
For physics: Thermodynamics, Current Electricity, Electrostatics, and Optics.
For Chemistry: Periodic Table, Chemical Bonding, Hydrocarbons, and Chemical Kinetics.
This chapters are the highest scoring in jee main. Hope this will help u. Wish u good luck.
Hello,
If you are currently studying in Class 12 and haven’t yet received your registration number or roll number from your board, you can leave that field blank or enter “NA” (Not Applicable) in the JEE Main application form.
Once your board issues the official registration or roll number, you don’t need to worry, NTA verifies your board details later during counselling or admission, not during registration.
So, do not enter random numbers, use “NA” or skip if optional.
Hope you understand.
Hello,
No, this small spelling difference will not cause major issues in JEE Main registration . But it’s better to keep your documents consistent to avoid any confusion during verification.
You can prepare an affidavit stating that both names, Girisharadhya and Girisharadya belong to the same person (your father). This is a valid and accepted method.
So yes, making an affidavit is perfectly fine and will solve the issue. Just keep a copy of it with you in case officials ask for clarification.
Hope it helps !
Hello,
Yes, you can correct the wrong APAAR ID later during the designated JEE Main correction window by logging into the official NTA website and accessing the correction facility. Here in this article you will find more info about this query.
I hope it will clear your query!!
