Hi Pratiksha,

Firstly, if you are from the general category, then you need to be in the top 20 percentile in your board because you have not secured an overall aggregate of 75% which is necessary for IIT, NIT or IIIT.

But, if you are from sc, st or obc, then you have passed this criterion.

According to your percentile, your rank would be around 75k which is not bad but not good enough to secure a rank in any NIT because you need a rank below 50k to stand a chance.

You can also check the cutoff of all nit's from the given link-

All the best!!!
