Hello RAJAT Chaple

As you have scored 70% marks in boards that means your probability of NIT is 0.5

So, you can apply for some of the private colleges of west bengal and punjab too!

You can also seek out for some private colleges of bangalore.

Though your rank will not let you land onto the top colleges but you can get some of the average decent colleges of WB or punjab.

Hope that answers the question!
