Hello Sourav,
As per your rank, your chances are very slim for getting BIT-Sindri, but wait till the last round of counselling as many students release their seats, so you may have chances to get any lower branches there.

You have a very less chance of getting into Birsa Institute of Technology, Sindri (Dhanbad).You should have a rank of under one thousand to take admission in BIT-Sindri.

For mechanical engineering, the rank range is 3100 to 5500. For electrical engineering, rank range is around 4700 to 6100.
These are just tentative, actual ranks may differ.
