JEE Main 2019 Paper-1 Answer Key for January 11 by Career Point (Forenoon Shift)

Heya,

Yes, you can refill your category again. In the case of the April session JEE Main registration, you have the option to change your category while registering your details only once. You can switch from General to EWS if you have a proper certificate. Just be certain that the EWS certificate is granted before the last date of the April session form and complies with the NTA's requirements of validity.

Hope it helps!!!

if we talk about DTU (Delhi Technological University) — you must have at least 60% in PCM and pass all subjects. The 75% rule is not strictly applicable here, so you can get admission based on your JEE Main rank and Delhi quota, if applicable.

For IIIT Hyderabad, admission is based on JEE Main percentile/rank, but the institute also requires a minimum of 60% in Class 12 (PCM). So, even with less than 75%, you are eligible if you meet this 60% requirement.

Hope you understand. ALL THE BEST.

Hello Tanishka,

Although i believe your attempting strategy and sequence depends entirely on your stage of preparation and your personal progress, i would suggest you sit for your January attempt even if you aim to seriously prepare for April.

Whatever stage of syllabus completion you are at, i suggest you give it a try to get an estimate of the exam difficulty and see roughly where you stand among the applicants that year. No matter how many mock tests you attempt, the actual examination environment happens to be very different from mock tests. The first attempt is going to give you an idea of the exam environment so you can prepare for your April attempt better.

All the best for your exams!

Hello Swati

Yes, your EWS certificate will be valid for JEE Main 2026 and counselling if it’s issued after April 1, 2025.
This is because EWS certificates are valid for one financial year from April to March.
So, a certificate made in October 2025 will be for FY 2025–26, which covers both JEE and counselling. You’ll need the certificate number during JEE registration in October 2025.
Even if you don’t have it yet, you can still register and upload it later during counselling. Just make sure the certificate clearly mentions the correct financial year.
Always keep a few extra copies and the original ready for verification.
You're good to go if it’s issued after April 1, 2025

COMPETETIVE EXAMS in the modern world are driven by the two modes of preparation, online and offline. While offline institutes offer you excellence with their old reputed brand names, Online institutes show fast pace learning and personalized planning.

Online Coachings are better if you want to

• Save time of travel
• Get quality education on a cheaper price point
• Get class recordings, to review your leanings
• Learn at a steadier pace
• Skip the chaotic environment one might find in an offline institute.

offline institute offer a physical teacher but as it has been seen from a general trend that students do not understand in their regular classrooms, and later learn from untrusted online sources further degrading their level of preparation.

Hello,

Yes, NCERT books are good for the JEE exam, especially for building a strong conceptual foundation and for chemistry, but they are not sufficient on their own for high scores. NCERTs are essential for understanding the basic concepts of physics, chemistry, and mathematics, and many questions are directly based on their content, particularly in inorganic chemistry.

I hope it will clear your query!!

Hello,

For PHYSICS:

1. Concepts of Physics by H.C. Verma (vol1 &2)

Hello Hitesh

• A state EWS certificate is usually not valid for JEE Advanced or JoSAA counselling.

• You’ll need an EWS certificate in the central government format, as required by IITs.

• Even if issued by your local authority, it must clearly mention it’s as per Govt. of India norms.

• You can visit your tahsildar/revenue office and request it in the “central format for JEE.”

• Make sure the issue date is after April 1, 2025, for it to be valid in 2026 counselling.

• You don’t need it at the time of JEE Main, only during Advanced registration and JoSAA.

• You still have enough time to get it updated, so no stress, just don’t delay it too long.
