Politics is a much more enjoyable course overall than English language- although do note, the comment on practically knowing all the content is perhaps rather ill-thought out- although you may have an idea about the broader area of topics, there are some rather challenging niche sections, which a quick flick through the spec doesn't indicate. Then again, if you have a passion for it, and want to pursue it at uni, it is wholly a more appropriate subject choice than Eng Lang. I will admit, it's definitely the easiest of my subjects, compared to Eng Lit and History, and so, if you're looking for an easy A or A*, this is inherently much more suitable. Do remember however, that politics is an essay subject, just like History, and so just knowing the content isn't truly correlated to getting highest grades. There are no short answer questions on the paper, instead three 9 markers, and two 25, and so if your talents do not lie within humanities, perhaps assess that. I personally scored an A* in my mocks, and are predicted so, without that much in-depth revision, thus denoting the easier nature of the course. Honestly, politics is so much fun, and you will not regret taking it- as many of my friends who take Language do.
