Should I choose the course available in the university since not all courses are available in all language types in Ireland/Germany for a Master's?

Yes, you should choose a course offered in a language you are proficient in, as not all programs are available in every language.

In Germany, many Master's programs are taught in both German and English, but availability varies by university and course. In Ireland, most Master's programs are taught in English, with some exceptions in fields like Irish studies.

Since you plan to take the IELTS exam and have a background in Artificial Intelligence, focusing on English-taught programs in Germany and Ireland is recommended to meet admission requirements and fully participate in your studies.
