Hi Ramprasadh,

Yes, there is an increase in the total number of seats available in NIFT for B.F.Tech from 360 to 425. Considering the level of competition and the number of aspirants applying for the entrance examination it is very difficult  to confirm that the cut off marks will decrease. B.F.Tech course is recognized course offered by nift but the number of colleges offering this course with respect to the number of colleges offering other courses is less. At the end the wanted level consequently increases. Keeping this in mind only NIFT has increased the number of seats offered in this course. 

Be confident and give your best in the GAT and try to score high and increase your chances of obtaining a seat in NIFT , Delhi.
