I’d say that it was not that hard because I was confident in my English, and I could understand a lot, and I watched a lot of movies in English. It was hard in terms of exams because when you’re passing the exam in a non-native language you had a barrier of knowledge of the subject plus a barrier of knowledge of the language, because there’re a lot of specific words that you just had to remember. So, it was a little bit harder than Russian exams but in general I didn’t see any difference during the lectures or during the studying process or even like during my life there.
