Hello Shubhangi,
Law and CS are unrelated courses, and for the best results and placements, you should focus on them individually- take up a full time LLM and go for a CS diploma on the side at most. Or, you could do part time/distance learning courses on each of them.
But, it would be advisable to not juggle the two full time together.
