Hey, I'm taking Politics and International Relations as well. I just finished my exam for this year (IR1011 and PS1172). I can only take 2 per year because I work full time. I have no idea how I did because there's no tutor who can tell me if I write my essay correctly. The official forum there have other students who can help critic your essays. Also, you can download previous year's exams which have commentary to help you see what they want from your essays
