Hello Vikash,

Sorry to disappoint you but even to get admission into lower NITs you need to have a percentile more than 90% as a general candidate(If you are not OC it will be different). I would suggest you to rather take admission in private colleges that are affiliated to jee mains or if you want NITs only you can drop a year and come again next year with much better preparation.

To know what colleges you may get with this percentile I would suggest you to go through the jee main college predictor tool from the link given below

Hope it helps.

Thank you and all the best.
