I have already chosen business administration so cannot chose public administration. Business administration is easy for me and I am familiar with almost all the syllabus. Just need to revise the concepts.
I have no idea about international law. Suggest me a high scoring theoretical subject from group 5 or 6.

And I have gone through many past posts of international relations and political science. Every one is discouraging to attempt the both subjects. Which one is better choice?

What about accounting and auditing?
I have bachelors degree in it and I am doing masters in the subject. I have studied financial, cost, advance accounting, business taxation and auditing briefly in bachelors. Can a person who does not hold a master degree in the subject attempt the paper? What do you say?
