It 12586 rank under ews category  can I get into nits and iiits??  Suggest me few colleges yours are most genuine reports

For NIT your rank in JEE MAINS will matter. As such your rank is quite descent thus you will get a good NIT. But to get through an IIT, JEE ADVANCE needs to be cleared with a good rank so that you can get to an IIT. So all the best for your JEE ADVANCE.
