How much will be required for aiims delhi And preparation tips for aiims delhi

Hello Aspirant

AIIMS Delhi admission is through the NEET-UG exam, and you need to score among the top 50–100 ranks nationwide for a general category seat. The cutoff marks usually go above 705+ out of 720 for open-category students. Start early, focusing strongly on NCERT books, especially for Biology, Physics, and Chemistry. Make a daily schedule with revision, mock tests, and PYQs (previous year questions). Stay consistent and avoid distractions. Concept clarity matters more than memorisation. Maintain your health and stay positive; persistence is the real key to cracking AIIMS Delhi. https://www.careers360.com/university/all-india-institute-of-medical-sciences-new-delhi

When will the nta jee mains correction window be opened I have not entered the school name properly and the I have entered the name of authority issued the obc certificate instead of designation can these two be changed

Hello,

NTA has not yet announced the JEE Main correction window dates. It will open after the registration process ends, and the notice will be released on the official website.

You can usually edit details like school name and category-related information during the correction window. So, you should be able to correct the school name and the OBC certificate authority field if those sections are made editable.

Keep checking the JEE Main website regularly, and make the changes as soon as the correction window opens.

Hope it helps !

Yes, you need to enter your board registration number while filling the JEE Main application form .

This is the number given by your school board (like CBSE, ICSE, or state board) when you registered for your Class 10 or Class 12 board exams .

You can find it on your Class 10 or 12 admit card, marksheet, or registration slip provided by your board.

I updated my name in Aadhar after filling the jee application, the aadhar is updated before submitting the application,so does the updated details will be verified with application name or not,as its showing name not verified still in the application application

HELLO,

The JEE Main application verification system uses the name you enter in the application form at the time of Aadhar Card verification so if you your Aadhaar was updated but still it is showing name not verifies then it means the new details have not been reflected in the online system use by NTA

Now what you can do is :-

1. First check the status of your Aadhaar card updates on the official UIDAI website by using your Update request Number.

2. Verify the details you have entered in application form like ensure that the name that you have entered in the JEE main application form exactly matches your newly updated Aadhaar card

3. You can use the NTA Mismatch Advisory like if a name mismatch pop up appears during the application process so for this NTA has provided the solution first close the pop up then a new window will appear that will allow you to enter the name exactly as it is on your Aadhaar card

4. If still the problem does not solve then you can contact the NTA Helpdesk

Hy Maine abhi tak koi preparation nahi ki neet ki or aab sirf es saal ko khatam hone mai 2 mahine bache hai kya mai acca score kar paungi abhi. Bhi neet mai

Hii,

There's still about 5 months left for NEET. If you study strategically and stay consistent and disciplined, you can crack NEET. But it's gonna be hard. You'll need to study for at-least 10 hours daily without any distractions. You'll have to make NEET your ultimate goal. Focus on the most important portion from the exam point of view first. Get a good hold of NCERT. Practice previous year questions. Take good care of your health. Study with sheer dedication and utmost discipline. Stay true to yourself. Try to complete your syllabus by March-end. Give mock tests regularly, especially in the month of April. Try to maintain a constant score of about 600 during the month of April. Have faith in yourself and instead of asking if you can do it, start doing it. Start working towards your goal and make yourself and your parents proud by actually achieving it.

I'm attaching a link from which you can access the important concepts for NEET. Start your preparation from there.

I had given class 12th board in 2025(get less then 75 percent) and also given improvement of class 12 in 2025 July session( in 1 subject and then get 75% plus), now I got seperate marksheet for that improved subject, so which total marks should I put in jee mains 2026 form filling?(Is that with improvement or without improvement )?

While filling the form of JEE Mains 2026 January session, upload the improvement marksheet, as your improvement marksheet is your final marksheet of class 12th AISSCE exams. The one that you got before the improvement doesn't matter now as you appeared for the compartment exam to increase your overall score. So, use the marksheet given to you after appearing for your improvement exam everywhere as that is your finalized class 12th marksheet.

my fathers name in my aadhar card and his aadhar card is Girisharadhya.but in my 10th marksheet is Girisharadya.Does it affect jee mains registration 2026.which name should I enter during form filling

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!
