Completely depends where you go. In my Political Science course we have four specialisations you choose in your second year: International Relations, Political Theory, Comparative Politics and Public Policy and Governance. You study different ideologies in almost every class, just to different degrees - mostly in political theory, but everything links to ideology in some way or another. International Relations is quite theory based, which is something lots of people don't realise until they study it. If you like to think about politics practically then you would enjoy Public Policy and Governance. I don't study in the UK, so there is no real reason for my course to be UK-focused, but I've found that lecturers use the UK as an example quite often. Most of our assignments allow us to cover any country or region we want if we can justify why it's relevant to the assignment brief. I usually pick the UK since I know the political landscape the best. If you want variety that's available too: we've covered France, Germany, Italy, Haiti, China, India and Latin America in some of our classes. I study in the Netherlands, so we are often taught about Dutch politics but the lecturers definitely make sure it's accessible to international students, and nobody seems to have an issue with this. We also have half our third year where we can study literally anything we want: take electives, take a minor course, study abroad or take an internship. You could study Political Economy, Art Restoration or Water Management if you really wanted to. It's worth noting that the course is taught in English. If you're interested in doing your degree overseas (which sounds more daunting than it actually is, mind you) just lmk and I can give you some pointers.
