Hi Raja,

Congratulations for receiving the Jadavpur University, since it is the most reputable college of the state. Now about your upgradation, you can surely apply for upgradation, if there is are seats empty and according to your choice list you have filled IT branch above than mechanical, then you might get the desired seat. Also once you get the college, after a year you can shift the branch if there is a empty seat. But there are definitely chances of you getting the IT branch in upcoming rounds. So try for it.
