I'm giving pak studies in may june 2018 and i am terribly prepared for it! I need some help in knowing the less important stuff in both history and geography so that at least I can get the important one done in time. so... is it absolutely necassary to learn the first chapter of history? the one about haji shariatullah, shah waliullah and syed ahmed barelvi?? or i can just go through it in the end before the paper?
