Geography vs Punjabi vs Any History
 

This is Usman and I am Petroleum and Gas Engineering Graduate, wanted to appear in CSS-2017.

I have opted following Optional subjects and feeling quite comfortable with them as well;

Physics (200)
International Relations (200)
International Law (100)

For rest 100 marks, considering :blinkthe fact that I have science related back, I [B]felt myself attracted towards;
Punjabi[/B] or[B] Geography[/B] or [B]any History[/B] (most probably[B] USA History[/B])

Can someone please advise and suggest me in choosing one subject as I shall be travelling to Pakistan in next month to purchase books etc..

Thanks in Advance!!!

Go for Punjabi or USA History as both of the subjects can be prepared quickly.
