PIYUSH, I will list down the top colleges you can get admission in under JEE Main. This is based on your rank and previous year cutoffs. You can try for admission in these colleges (decreasing order of preference):-

• National Institute of Technology Agartala
• National Institute of Technology Arunachal Pradesh
• National Institute of Technology Hamirpur
• National Institute of Technology Meghalaya
• National Institute of Technology Puducherry

But again it depends on the number of students who appeared for the exam and as well as the difficulty of the paper.

Feel free to ask if you have any more queries.

Hope this helps!

All the best!
