I am a dropper ..and i have got 75% in cbse boards..how much mrks do i need to dcore in jee mains to get a NIT ?

As per new pattern of JEE MAINS , 40% wattage of cbse board and 60% wattage of Jee Mains exam, Al-tough you have 75% in cbse exam, these are very less, so to comp-onset these you have to secure atleast 55- 60% marks in jee mains exam (if you are in Gen. Cat.) to get a good branch in good NIT. You can get NIT easily around if you score around 50%, but at this score you dont have much obtions.
