Can I change my branch in second year of engineering?
I think it's more related to which university you are into and what reason you are going to have to do this.
I have not seen guys doing this ever. Think about this one more time and see if you really have valid reason to do this.
That's right. Typically the University or the college will decide whether you are allowed to change the branch in the second year of engineering. It was certainly an option when I was an engineering student.
Which University / College have you been admitted to?
