I did not study computer application in 12 th as my 4th subject was physical education. Can i take cs in iiit bhubaneswar?

@ neelendra 
For sure , for entering into iiit bhubaneswar or any other iiit , u need to just get a good rank in jee as the iiit councelling will happen with josaa (joint seat allocation authority ) in which your jee main score will take into account , so, get a better rank there and u are in . the comp. sci is not as such required to take cs in any engg college . 
HOPE IT CLEARS YOUR DOUBT 
ALL THE BEST ..
