Its possible to cover it within 10 days but if you are taking constitutional law with it. Paper 1 of political science covers Western and Muslim Political Philosophers. You don't have to do all philosophers.Prepare Plato,Aristotle,Hobbes,Rousseau,Mill,Machiavelli and Marx from Western Philosophers.Since the examiner asks for a particular aspect of each philosopher's philosophy like Hobbes state of nature, Rousseau's General will and Marx's dialectical materialism...Just focus on them.Similarly prepare al-Ghazzali, Nizam,Iqbal and al-Farabi from Muslims Political Philosophers (the same rule applies).Also if you have time prepare al-mawardi.This will not take more than 3 days. Paper two comprises of World constitutions.So if you are taking constitution law along with political science it will cover your 7 constitutions.This will not take more than 5 days since one day per constitution is more than enough.This leaves you with two days.During this two days prepare general topics like Judicial review,types of govts,democracy etc.if you can give 5 more days to it you will be able to cover your whole political science course otherwise 10 days of preparation can give you 120 plus marks depending upon your writing skills. Best of Luck
