Hi Kaveri, hope you are doing well, yes surely your sister can get admission in gitam but can not get any of the concessions like 1-10 rankers in gate get 100% concession and 11-100 get 75% concession and 101-500 get 50% concession. This is the concession fee structure in gitam for the gate exam. Keeping aside all these things your sister can get admission in the gate.

I think it is helpful!!!

Keep Smiling:)

Wish you good luck!:)
