Hello,

IISC doesn't provide BE/BTech degree. JEE Main is an entrance exam which makes candidates to be eligible for engineering course which is given by government college, university, IIT/NIT/IIIT/CFIT and private institutes.

for engineering, IIT is the best and top college. if you want to join then you have to get a percentile above 90% for general category. for categorical reservation, what percentile will be considered is decided by the NTA board.

Hope it helps!
