Have a question related to JEE Main ?

Hello,

Yes, you may get a chance to correct it.
NTA usually opens a correction window before each session. In previous years, candidates were allowed to change their photo if it did not follow the guidelines, including background issues.

For JEE Main 2026 also, the correction window is expected. When it opens, you will be able to upload a proper photo with a plain white background.

What you should do now:

  • Keep checking your JEE Main login for any correction option.

  • Keep a correct photo ready (white background, clear image).

  • If NTA flags your photo, you can update it during the correction period.

So yes, you should get a chance to fix it once the correction window opens.

Hope it helps !

Hello,

That's the most efficient approach to preparation! The entire JEE Main Syllabus is fundamentally based on the topics covered in the NCERT Class 11th and 12th textbooks for Physics, Chemistry, and Mathematics.

Here's what you need to know:

  • NCERT is the Core: Approximately 60-70% of the JEE Main syllabus directly comes from the NCERT books. You must consider these textbooks as your foundation and cover every single topic and exercise.

  • Minor Overlaps/Additions: While most of the syllabus aligns, JEE Main sometimes includes a few concepts or deeper applications (especially in complex numbers, differential calculus, and some physics derivations) that extend slightly beyond the direct NCERT text, requiring extra practice.

  • Chemistry Exception: Physical and Inorganic Chemistry are almost 100% covered by NCERT. For Organic Chemistry, mastering the reactions and mechanisms taught in the NCERT is critical before moving to advanced texts.

You can download the PDF containing the complete, topic-wise JEE Main syllabus to cross-reference with your NCERT chapters here: https://engineering.careers360.com/download/ebooks/jee-main-syllabus . This linkage is your best study guide!

start by finishing the scoring topics in physics, chemistry and maths.. and revise them deeply through examples and pyqs.. spend 60% of ur time on topics that frequently appear in exam and the remaining 40% on weak areas.. give one mock test every week, analyze mistakes and create a revision book as well as formula book to keep revising the formulae and the mistakes.. plan ur schedule one week ahead and plan the concepts u want to study.. keep small milestones and reward urself constantly to maintain ur motivation.

‍‌‍‍‌‍‌‍‍‌ In case you want to have access to the handwritten notes made by the JEE toppers, the most convenient manner is certainly by means of proper platforms which share the study material in a legal way. A good number of toppers have their notebooks uploaded on some educational apps or YouTube channels, and a few coaching institutes may offer compilation notes either for free or upon registration. Also, you can visit official JEE preparation forums where students share their handwritten notes for the convenience of others without any charges.

When you are downloading notes, it is always better to check if the source is trustworthy and the files are genuine because if you take the incomplete or incorrect notes, it will have an impact on your preparation. A more secure choice would be to look at the toppers' plans and brief notes that are written in the form of books or PDFs by the known coaching institutes. Never forget to combine such notes with the questions of previous years and mock tests so that your preparation will be complete. ‍‌‍‍‌‍‌‍‍‌
