Hey aspirant,
For branch change at any of the BITS institutes, you will have to score a CGPA of 9.6 and above, which is not something easy to achieve. Change of branch also depends on availability of vacancy in each branch, which is very rare at BITS campuses. Along with this, you also will have to be lucky enough for getting a branch change. Apparently, the probability of being able to change branch at BITS is lower than that of IITs/NITs.
Hence, I wouldn't recommend you to join BITS for a branch you have no interest in and have plans to change branch. It would be better if you choose a branch of your choice, even if you had to choose some other college.
Hope this is helpful.
