There's this really good website called UniFrog and there you can put in all the details as in what course you want to do and what grades you have been predicted. Once you click search it will generate three categories of universities that are aspirational in comparison to your grades, solid and safe. You can choose different filters when looking at universities such as the with study abroad or russel group etc. However, I'm not sure whether you have to pay for having an account on there as my college provided it for us. If you're not able to get access to UniFrog I would suggest some in depth research on the top ranked universities for Politics.
