Hi lanchungpu,

See With the rank which you have provided , you may not get any NITs/GFTIs as per previous trends in JoSAA counselling. The Cutoff for these institutes usually hangs between 400-800 ST Rank list

Meanwhile it is advised to you to also fill up state level counselling forms like Of Chhattisgarh, Orrissa,punjab etc and other private institutes which accept jee scores for their admissions like SRM, Manipal,LPU,CBS ,CCA etc.

You can also predict your colleges with this college predictor tools from this link

Feel free to ask any doubts.

Good Luck !
