Learning German is not universally mandatory for studying in Germany, but it greatly depends on the program and university you choose. While many German universities offer an increasing number of English-taught courses, some programs still require a certain level of German proficiency. Learning the language can enhance your experience by facilitating daily life and cultural immersion. It also opens up more opportunities for scholarships and part-time jobs. So, while it's not an absolute necessity, considering some level of German language skills can make your academic journey and life in Germany smoother and more rewarding.
