\frac{4}{x} \log \left[\frac{k_2 x+1}{k_1 x+1}\right] & x=0 \\
& x>0
\end{array}\right.
$
Then $k_1^2+k_2^2$ is

2. Physics Section
As compared to previous years, the structure of the JEE Main 2025 January 23 shift 1 exam is expected to be organized in the same manner as the major emphasis on the distribution of questions. Mathematics will remain a focus of Calculus and Algebra, and Mechanics and Electromagnetism will dominate the Physics portion. Hopefully, Organic Chemistry will continue to be the largest section in Chemistry as it was in the previous years.
Frequently Asked Questions (FAQs)
The JEE Main 2025 January 23 Shift 1 Question Paper and Solutions will be provided here after the conclusion of the exam. Students and teachers can access the question paper in PDF format.
The JEE Main 2025 January 23 Shift 1 exam is expected to have a moderate difficulty level and a balanced distribution of easy, moderate, and difficult questions across all sections. Mathematics and Physics are likely to be comparatively challenging and the Chemistry section is expected to be easier for those with a strong foundation in Organic Chemistry.

Hello,
You can get the JEE 2025 Syllabus from this link : JEE Main Class 12th Syllabus 2026
Hope it helps !
Hello,
You cannot "renew" your September 2025 certificate. You must apply for a completely new EWS certificate after April 1, 2026.
EWS certificates are linked to a specific financial year.
Your certificate issued in September 2025 is valid for the financial year 2025-26. It is based on your family's income from the previous financial year (i.e., 2024-25).
The certificate required for JEE counselling in mid-2026 must be valid for the financial year 2026-27. This certificate must be based on your family's income from the financial year 2025-26 and must be issued on or after April 1, 2026.
Since they are based on two different income periods, they are considered completely different documents.
Hope it's helpful to you.
Hi! Don’t worry, you can correct your category this year while filling out the JEE Main 2025 application form. If you belong to BC/OBC category and have the valid caste certificate, you can apply under OBC NCL now. It will not be a problem if last year you had applied as General/EWS, since each year’s application is considered separately.
OBC NCL is for candidates from socially and educationally backward communities (non creamy layer) with income below 8 lakh, while EWS is for students from the general category (not SC/ST/OBC) with family income below 8 lakh. Since your family income is less than 2 lakh and you are BC, applying under OBC NCL is the right choice and will give you reservation benefits.
Hello,
To get below AIR 100 in JEE Advanced 2027, you need a strong and focused plan. Here’s a simple guide:
Clear Concepts : Make sure all NCERT basics are strong. Focus on Physics, Chemistry, and Maths concepts deeply.
Advanced Practice : Solve previous years’ JEE Advanced papers and high-level questions from books like HC Verma, I.E. Irodov, OP Tandon, and Cengage.
Regular Mock Tests : Take full-length tests every week. Analyse mistakes and improve weak areas.
Time Management : Learn to solve questions quickly and accurately. Work on speed and accuracy together.
Short Notes : Make notes/formulas for quick revision.
Consistency : Study daily and avoid long breaks. Consistent practice is key.
Focus on Weak Areas : Identify topics you struggle with and spend extra time on them.
Stress Management : Stay healthy, sleep well, and avoid last-minute panic.
If you follow a structured plan and stay consistent, AIR below 100 is achievable.
Hope it helps !
