Hello aspirant.

Thanks for choosing career360.

There is nothing such kind of specialisation before going to btech and choosing cse but u must be knowing some basic languages for ur benefit because in college there is no time to learn these old things which u must be knowing in early days.

In cse branch u r facing a next level ofjust knowing the coding and the doing simple programs.....that's why if u know Java or C++ it is sufficient.

For other queries please ask.

Good luck
