Hi

I am assuming that you belong to general/obc category.

You are not eligible for  nest examination with your date of birth in 2000.

This is because,
As per eligibility criteria of nest examination , there is age limit according to which those who are from general/OBC category must be born either on or after 1st August , 2001.

But yes,

In case if you belong to Sc or St or pwd  category then with your date of birth in 2000  you will be eligible for NEST examination because for SC/ ST/ PwD category there's a relaxation of 5 years on age limit.

You can get detailed information about nest 2021 eligibility criteria by visiting our page, the link for the same page is provided below  :-

Thank you

Dear aspirant,

I would be giving you the information about the exam pattern after which you will be crystal clear of your mind.

The duration will be of 3.5 hrs. There are multiple choice questions. There will be four sections. Section 1 has 50 marks and section 2-4 has 50 marks each. So the total is 200.  There will be negative marking too. For every wrong answer 1/4 marks will be deducted.

For more information you can check out the link given below-

Hello,

The NISER and UM-DAE CEBS has extended the deadline to fill NEST 2021 application form till May 20 but there is no information regarding the postponement of NEST 2021. So as of now the entrance exam of NEST 2021 will be conducted on June 14, in online mode unless there is any information regarding postponement form officials. Keep an eye on the official website for the latest information. Candidates will be able to download the admit card of NEST 2021 from June 4 in online mode.
