How do I set myself apart from other people taking the exam, so I get a higher grade.

Well, in Politics in particular, examiners are looking for evidence that you are a student that understands and can talk confidently about complex political phenomena. Do this by making it clear that you know that there are many competing explanations of things and that you realise the issues at play, this will show ultimately that you have a better understanding of the world and so deserve a better grade. When revising, look for these debates and for good examples for your points, and try to think about some reasonable conclusions that you can have in the back of your mind for the exam. To exemplify what I mean by , lets take a political ideologies question on Feminism. A recent one from 2016: ''More things divide feminists than unite them'. Discuss', it is vital that you emphasise how broad Feminism as an ideology and movement is. Feminists have ranged from people adopting 'political lesbianism' in communes in California, right through to modern day 'lifestyle' feminists, concerned mainly with pay gaps, catcalling and domestic violence. Your answer needs to reflect this. Tone is very important too: examiners read loads and loads of papers and will be making quite quick decisions about where you fit into their grading system('is this student an A or a B student?'). If you write to the point with good clear, authoritative phrasing with good examples, they will find it easier to stick you into those categories(this links into a wider point: try to think like an examiner). Practising writing essays and reading books will help you learn this. You have a wonderful human brain that just needs practice with this stuff, practice and you will get better at it. A lot of these things here are things that all too many students do not do. Do them and you will stand apart.
