With this rank you wouldn't be able to get admission into NITs and IIITs moreover getting top private colleges would also seem difficult for you. But you could get admission into other private colleges that accepts jee main score or if you want admission in government colleges only then I would suggest you to come again next year with better preparation.

You can predict what colleges you might get with this rank by going through the link of college predictor tool given below.
