International Relations II = 30 % European History 20% Intl Law and 50% Current Affairs.
International Relations I = 15 % I Law ( as a chapter) rest 85% is IR Basics.
If one has EH, ILaw as optionals, he will need to prepare for just 85% which are basics.

This analysis of mine is the sole reason of my preference of IR over ACCOUNTANCY.

Dear Seniors, I also look for your precious guidance over this analysis done by me.
