I need your* kind suggestion please. I got confused after attending Kips class of International law(introductory class).I found the aforementioned subject really interesting for myself, although I had bought books, studied little bit History of USA and I had already made my mind for history of USA (which is short and high scoring) but now I want to alter it with INTERNATIONAL LAW. What about environmental science subject for a Science background candidate?
My background is Master in physics and the rest of my* optionals are ;

PHYSICS (200)

INTERNATIONAL RELATIONS (200)
PASHTO (100)

HISTORY OF USA (100)

OR

INTERNATIONAL LAW (100)

What do to now?
I will be highly grateful if any experienced person help me out of this perplexity.
