Hy Sintu Pal!!

Yes ,of course, you can do ma in Sociology after being graduate in BSC with PCM. There is no criteria of doing MA after being graduate in Ba. The only qualification is that you must have at least 50% marks in your graduate degree to be eligible to apply for Ma in  sociology. This is an emerging field having enormous career options ahead. If you have interest in this subject, you can definitely go on with it.

If you still have any further doubts feel free to ask.

Good luck!!
