Is it important to learn German to study in Germany ?
It’s not necessary to learn German to study in Germany but it’s highly recommended. There are some Universities in Germany that give you the opportunity to study in English but eventually once you go into the job market you would have to definitely learn German.
So if you’re from IT you’ve more chances of finding a degree offered in English. But if you’re in some other field like doctor, business ( MBA, BBA … ) or some other stuff than the chances become less.
