Hey Nitish,

All the branches CSE , IT and ECE are good.

IT and CSE are almost same since IT is a part of CSE so will find some syllabus will be missing in IT.

you will learn hardware as well as software in CSE while in IT you will study only softwere so there are more jobs in CSE than IT.

ECE is different than CSE/IT but maximum number of students are study softwere and get jobs also companies higher ECE students because they have knowledge of softwere as well as electronics.

In some year demand of ECE will increase.
