Greetings!

With two years spent in specialization in college(till now) I can tell you that there is no difference between IT or CSE with specialization, the only reason why these specializations exist at Btech level is because of a certain limit set by UGC that you can not take more than X number of students in one branch. To get around this rule these specialization were made, as there was more demand for CSE related seats.

In total no matter what you pick there will be only 4-3 subjects that will be different in entire 4 years... So if you have a specific affinity for any specialization you can go for it, otherwise no matter what you pick it is going to be the same only.

To explore more options you can use the following predictor
