It’s a good option - my D initially was quite set on going there as she had spent a summer in Germany an loved it. There aren’t that many undergraduate programs offered entirely in English so German proficiency is required. (Though we did find one smaller university with all English programs.) In the end, she got a nearly full scholarship to a top US engineering school so went there, and might go to masters or pHd program in Germany instead (which has many more options in English), TUM or Berlin would be great. (Personally, I’m hoping she’ll go to Zurich.)
