study some history books like Indo Pak History ki PROF. K ALI & Pakistan-the real picture by Rizwana Zahid Ahmed....
don't spend all of your time there coz usually it accounts for only 20 marks ..

After having basic knowledge & facts and figures .. study articles in newspaper , keep an avid eye on current affairs & try to have gist of almost every topic related to pk. specially IR and role of Pk in global scenario ..

keep in mind , its not simply an exam to write what you have crammed rather it judges your quality ;to analyze critically and that of your judgment..... it tests your ability of how percipient you are, how much knowledge do you have and how well you can handle the question comprehending the very spirit of it..

in a longer run reading newspaper helps you in almost every subject..
one of an ASP of my acquaintance used to say that reading English newspapers and articles help you in every paper & she thinks it accounts for 70% of CE .. I too agree with her after my experience in CE2016
