If I got seat in iit by jee advanced, I want to pay money for my course like 8 lakhs

Hello aspirant,

Please get this straight that admission to NITs and IIITs is nowhere related to JEE Advanced score. Hence, if you are targeting NITs or IIITs for any of the engineering branch, do not fret about your JEE advanced score. If youre targeting IITs or ISM then you need to look out for JEE advanced score.
Admission to NITs and IIITs is based solely on your JEE Mains score. And, a minimum percentage of 75% is required in 12th boards.
Here is how it works: You will be admitted into an NIT through CSAB (Central Seat Allocation Board) on the basis of your JEE mains score. An All India Rank is given to the candidate based on his score and he/she will be asked to pick his/her choices among NITs and some other private universities. So, if you have a good enough rank in JEE Mains, you will have a high chance of getting into a good NIT.

Hope you understand,
Thank you
