Hello Aspirant! BIT Sindri is a government college in Dhanbad, Jharkhand. Only qualifying JEE Main won't give you the key for getting admission at BIT Sindri. You must have a Residential of Jharkhand to prove that you're from Jharkhand as only students who are from Jharkhand are eligible for admission at BIT Sindri. No other states are eligible for admission in this college. You must be from Jharkhand and have a residential and you also need to qualify the cutoff marks of the same.
Hope this helps.
