Hi

Which top nit?

Let's take the case of nit Trichy which is the top most nit among all nits, and let's considering computer science branch which is the best branch

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 2021 , for  gender neutral to get computer science engineering   , closing rank  in NIT Trichy is given below :-

OTHER STATE

Category                      closing Rank

General/open                   714

You can check the same at

So, for other state, for general category, you should target at least around 714 rank i. e around 280 marks as  predictor at
