Hello Aspirant,

According to the percentile you have mentioned in the question you cannot get any of the NITs as per previous year's cut-offs but I would suggest you to sit for some state counselling because in some of the state government colleges you can get admission on such ranks. Also you have been qualified for JEE-Advance as you have mentioned in the question so for getting any of the good IIT you should try to secure your rank under 10,000.

Note that the cut-offs are bound to change every year depending upon various factors.

So you can use JEE-Main College Predictor to predict your chances of admission in different engineering colleges of India :-

Good Luck!!
