Rohith, you have a good chance of getting BioTech. in IIT Kharagpur. This is based on your rank and previous year cutoffs. The branch closes at around 3100. But you can definitely get the 5 years course of BioTech there. 

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

For more information, you can refer to :-  https://www.careers360.com/university/indian-institute-of-technology-kharagpur

Feel free to ask if you have any more queries.

Hope this helps!

All the best!
