Hi

My optional subjects are following

International relations
Environmental Sciences
History of USA
Psychology

now for the final subject, I want to choose among Philosophy and International Law. ( I don't have a background in either of these subjects)
- I find philosophy interesting, regardless , International Law can help me in International relations as well ( as far as I have been told)

What would you suggest me, What would you do if you were in my shoes.

Kindly guide me here.

Regards
