Yes, it will definitely help you.

First, lets be clear about few basic fundamentals about IT and CS:
1 Information technology or IT is all about Software only
2 While on other hands Computer Science or CS is about Sofwtare Hardware and OS core
So, this is the reason why CS cut-off is going so high. Now, before Joining any college or university, please check the placement percentage and type of companies coming in campus and infra of the campus as most of the universities tell you that we have 100 percent placement but actually, they do not have good placement.

I think, you'll get IT most probably and not CSE.
