Hello!!!

As you mentioned that you didn't get cse in the very first round. Let me be very frank with you. Now the chances of you getting cse in further subsequent rounds are minimalistic because there are many students who have opted for cse . And once they have got that branch , they are probably not gonna leave it. So there won't be any seat left for you in next rounds. Cse , ECE ,IT  are such branches which get filled immediately. And if you didn't get them in round 1 then it's difficult to get them in round 2.
