Hello 

Your expected percentile score may be around 92.71( Will vary ).And rank will be around 81619(Will vary).

So you have to wait till exact results come.

But this is not a good score for jee advance.But if you cross the cutoff than you will be able to give jee advanced for IIT .But for NIT you have to prepare more hard.There are other options also like

State government ; or private college.

Otherwise you have to take drop.

Good luck :-)
