Hi Ruchika. Hope you are doing well

Since you have mentioned your obc rank I am expecting you to be an obc ncl (non creamy layer )candidate. According to the homestate cutoffs of 2019, NIT Durgapur CSE closed for male candidates at 13k (obc ncl rank) and for female  candidates at 19k .  For IIEST Shibpur ,it closed for male candidates at 13k and for female candidates at 17k approx.  So, you will able to secure a seat in any of the  two colleges according to your preference.

Best wishes
