JEE Main

Hello AYUSH yes, a student needs to register only once on the website of NTA for JEE Mains. However, if you have applied to appear in all possible attempts and paid the required fees, then you have to do nothing. Registration is open only for those who did not register in the beginning. However, if you had opted to pay fees and opted to appear only for the February examination then you need to skip the registration part and pay fees for the March attempt along with selecting the exam center etc. Best wishes to you.

Hello,
Those students who have already applied for all the four sessions of JEE Mains need not register again for the exam that will be conducted this month. The national testing agency has opened its portal for registration basically for those students who have not applied or registered earlier and wish to do it now. I am attaching a link that will further amplify what I am saying and also clear your doubts if any. https://www.shiksha.com/b-tech/jee-main-exam-application-form
Best wishes to you.

As per the last year of trends in consideration, your JEE Main All India category rank should be below 3482 for getting admission in NIT Calicut in B.Tech CSE. So you have to score above 99.5 percentile in JEE Main.

Hello K Manju, National testing agency is the one which conducts this examination. They have already completed first set of examinations scheduled for the month of February 2021. They are going to conduct this examination again in the months of March April and May. You can register yourself by accessing their webpage for registration. Best wishes to you.

Hello, these days the ranking of JEE Mains is not decided on marks scored but is decided by the percentile that you will get. Hence raw marks have list their importance. As far as ranking is concerned you need to be in top bracket to get admission in your desired branch of CSE. You can Google to find out different cutoffs at various NIT's. Best wishes to you.
