Hello Rakesh,

As you are aware that, for selection in different like IIT- Delhi, Madras, Bombay, IISC- Bangalore etc. and different NIT's., Gate score is required. Score required in IIT is higher than required in NIT. In general, if we see, gate score required for structural engineering is highest, followed by geotechnical engineering, construction management, transportation, environmental engineering, water resources engineering, rock engineering and so on. But this sequence is not fixed as well. Some institute are famous for particular specialization and may have higher cut off for it. It also depend candidate choice as well.

I hope this was helpful

Best wishes for future endeavors!
