Yes, you can study in Germany without knowing the German language. In Germany, many universities provide bachelor's and master's programs in English, particularly in engineering, business, and info tech. If you meet the English language needs, shown by IELTS or TOEFL scores, you can study without knowing German. Still, learning basic German is encouraged for daily life, part-time jobs, internships, and fitting in socially. Some programs have free or cheap German classes. German is not needed for English programs, but knowing it can help your career and cultural life.
