@ naila: dear i would once again advise u to go for general stuff, as if u were preparing for short questions or mcqs. no need to go for deep study. u should know about the main bodies of the un, no. of its articles, the icj's jurisdiction etc. hope it will b sufficient.

@ sajid sb: dear i m really impressed. it was a good effort indeed. i hope u'll get ur desired group this time insha Allah.
do remember me in ur prayers as well.
