Hi

I am considering you from general category as you have not mentioned your category

This is a bit difficult to predict the marks/percentile/rank required in JEE mains to get a seat in nit as cut off  keeps changing every year  depending upon various factors like  number of students that appeared in the exam, kind of marks obtained by them , toughness level of the jee main examination , number of seats available for the branch you want etc.

When we go through previous year trend then ,

In round 6 of josaa counselling 2020 , for general category  to get IT branch , 147055  was closing rank for females under home  state quota in nit srinagar

You can check the same at

And  147055 rank is roughly around 55 marks ,for this rank vs marks you can refer to our page, the link for the same is provided below

But yes cutoff keep changing every year, so to be on the safer side target at least around 70 marks  in your jee main 2021

Now, limited time is left for jee mains 2021 , so focus on your preparation, to prepare well for your jee examination, go through chapters first and your focus should be on grasping concepts , practising questions and then revising them, go through mock test paper sample papers and previous year question papers as it will let you know your preparation level and and weak areas so that you can work on them and perform well in your examination.

If you have any other doubt then you can always reach us to clear them :) we are always available to help you out and guide you

Thankyou
