LLB course is a hardcore law course and your BCA will be of no use anywhere. Doing a non-relevant post graduation is always an insult to the graduation you have done.
The most appropriate postgraduation for a BCA candidate will undoubtedly be an MCA. Of course, if you have done BCA seriously and with a proper choice at the time of taking admission to it. If you wish to completely change the field, then you can think of LLB as an option.

Yes, you can. Only your admission will be the process there, rest everything will be the same. I've seen many of my friends changing colleges for BCA and they could do it successfully! Good luck!
