Hi

With your percentile score,

your rank is given by

( 100-your percentile score ) * Total number of students that appeared in JEE mains January session /100.

= (100 - 82   )*869010 /100

=  156421

With this rank , you cannot get a seat in NIT Rourkela. For example,  last year a rank of 10531was required for OBC category for electrical engineering under home state quota in NIT Rourkela

So , to get into NIT Rourkela you need to get around 98.5 to 99 percentile in your JEE mains July session i.e around 170-180 marks

To prepare well for july session , follow the below tips:-

Go through your syllabus  completing each chapter , you should go through mcqs and numericals of the same chapter

Make short notes of important formulas and concepts for each chapter and Keep revising it

Solve previous year JEE MAINS questions , it will let you know the examination pattern, type question etc so that you can prepare accordingly
