The article you have written above is good for your first attempt. But now the pattern of the current affairs paper has been changed. So there wont be a question like

What is Kashmir Problem? Explain in detail

So you need to prepare topics from various dimensions in order to secure maximum marks. For example, question regarding Kashmir could be

India accuses Pakistan of exporting terrorists in Jammu Kashmir as a State Policy? Elaborate and should Pakistan revise this policy??

Or

How the endorsement of Obama for Indian membership in UNSC affects Kashmir dispute? (2011 paper question)

So you need to prepare the Kashmir dispute keeping in mind the recent developments.

I would suggest that you go through all the past 10 year papers. Read the following for getting better perspectives and historical contexts of certain events


1. Daily Dawn or News
2. Jahangir World Times Magazine
3. Current Affairs digest by Imtiaz Shahid (Bi-monthly)
4. 1 hour for TV Talk shows (if there is a good topic debated)
