I'm an indian student and I want to apply for an engineering course at ETH Zurich. I dont understand German AT ALL and I want to know if getting into ETH is worth the effort i'll have to put in to learn the language. Also, how much time does it take to be good enough at german to understand what's going on in class? And do i just have to get a C1 level certificate or do i need to take an extra course to learn scientific terms in german? Is it better to just enroll at a college in an english-speaking country? I'd really appreciate some help
