IIT

its just 72 marks out of 504. mins only 12% around. but you should have to clear minimum subjectwise cutoff

First you have to appear in both paper 1 and paper 2 of jee main. And have to clear paper 1 and a min. score in paper 2 which is not hard to get. Then you will also have to qualify jee advance after that finally you have to appear for AAT (architecture aptitude test) you need to clear that too. You will get admission in IIT roorkee and khadagpur exclusively on the basis of AAT none other score will be counted.Good Luck.

Hi
As per the data available for last year, out of 10000 seats in IIT, 4900 are for open category.

You can get admission in engineering collages of state and some private colleges also.
