Curriculum at university: international relations and global affairs

Hi everyone, I will be glad if someone could explain to me how it is difficult to study that curriculum at university. I go to a language highschool and this year I got also the cae certification, which is requested to follow that curriculum at university. I don't speak English so fluently because we didn't practice speaking at school :(. But I understand without problems! The subjects of this curriculum are: history of political institutions, political science, principles of economics, public law and system of governance, quantitative mothod for social science, sociology and advanced English. Last but not least: the course is international, I will have Italian and foreign colleagues. Looking for advices and past experience with these kind of subjects and university curriculum, thank you!
