Hello Naveen Kumar,

First of all congratulations for getting 99% in ISC Examination. Now getting on to the point, with a rank of 151001 getting admission into NIT and GFTI would be very very difficult. First of all with this rank you will not be able to opt your desired stream second the quality of college though it is GFTI will not be good. Instead you should go for state entrance examinations and there try to get into a good state government college. 

I hope you understood this.
