Sir,i got 70 in jee mains.I belongs to Bc category.My cbse board weightage is 90%.Will i get a seat in NIT.If so in which branch?

You scored well in CBSE.As you secured 70 its very difficult to get in to top NIT’s.So try to take admission in top privite University so thst they provide you excellent placement,good scholarships,enhancement in communiccation skills.

Those Universities are

Birla Institute of Technology
Manipal University
Lovely Professional University
Delhi Technological University
