With this rank you wouldn't be able to get admission into NITs and IIITs as for that you  need to score below 20k 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.

To predict what colleges you may get with this rank use the college predictor given below,
