I would suggest you to prepare Current Affairs in two phases: International issues and National issues.

As regard the International issues you must acquaint yourself well with:
1. Relations of Pakistan with all the four adjacent neighbours as well as its ties with America.
2. Relations of America with Iran, India, China and Afghanistan.
3. Organisations of the world, especially UNO, EU, OIC, SAARC, ASEAN and SHINGHAI CORPORATION.
4. Globalisation.
5. Global Warming.
6. Middle East with special focus on Palestine-Israel issue.
7. New Great Game.

For National issues you must go through the topics like:
1. Corruption.
2. Economy.
3. Water and Energy Crisis.
4. National Integration.
5. Balochistan Crisis.
6. 18th amendment.
7. Media.
8. Judiciary.
9. Democracy and Military regimes
10. Terrorism.

Dear these topics should be prepared in analytical perspective, having full background knowledge of the above topics plus the latest developments.

As far as the source to prepare the prescribed topics is concerned you must avail all the opportunities at your hand, ranging from history books to newspapers, TV Channels and Internet.

Best of luck and also pray for me as I am one of the ambitious aspirants.
