Hello,

To prepare for the JEE paper 2 or the Architecture exam, you need to understand the exam pattern and syllabus clearly. Then strengthen the fundamental concepts with daily revision. After that, take a mock test and practice with the PYQ to get the exam-like experience.

I hope it will clear your query!!

JEE Main exam is a national-level entrance test for admission into top engineering colleges like NITs, IIITs, and GFTIs. It mainly tests your understanding of Physics, Chemistry, and Mathematics. To prepare well, focus on NCERT books first, then refer to standard JEE preparation books for deeper concepts and practice. Regular mock tests and solving previous year papers also help in improving speed and accuracy. I’ll be attaching some useful JEE Main preparation links from Careers360 to help you get started.

Hello,

Generally an income certificate isn't required for the JEE Main registration, but if you want to claim the EWS quota, then you need this. You must provide the certificate, issued by a government authority, as proof of your family's income being below the specified limit for the reservation category you wish to apply under.

I hope it will clear your query!!

Yes, as JEE does accepts improvement examination scores, so you must go for it but most of the state boards have already conducted or are conducting their 2025 improvement exams. If you have already given your improvement that's fine. If you have not given improvement this year then you can take your improvement next year.

Thank You.

Hello,

Yes, you can prepare for and take the JEE Main exam after completing your intermediate (12th year) exams. This is a common path for students who want to dedicate a year to intensive preparation without the pressure of simultaneous board exams.

I hope it will clear your query!!
