The subjects which you have opted History of USA, Gender Studies are easy and scoring but Political Science is not so good, and one thing keep in mind that you should opt overlapping subjects which can fetch you good marks and also help you in other subjects particularly in Compulsory subjects like International Relations, International Law and History of USA, these four subjects are highly recommended and overlap each other plus help in Current Affairs. Firstly, you should go through the past papers and syllabus of those subjects that you want to opt, it is available on the fpsc.gov.pk and make your mind according to scoring trend and length of subjects plus your interest. If you have background in English Literature and interest then go for it. So my advice to you is you can opt International Relations, International Law and History of USA, English Literature and Sociology or your regional language. :
