Hello Aspirant,

As you have not mentioned the name of examination for which you are seeking guidance so it is little bit difficult to guide you accurately and help you with the exactly information but however considering your profile you are an engineering aspirant so you might be asking for JEE-Main. According to the marks you have mentioned in the question your percentile would be in the range of 98.59 - 98.79 and your rank would lies in between 11011 - 13161. On the basis of this rank and percentile you can get into good NITs like NIT Bhopal, NIT Uttarakhand, NIT Calicut and so on as per previous year's cut-offs. You can check out the cut-offs for top NITs from the link given below :-
