There are many ways to learn a language nowadays. I know people who download apps and have a great experience with it. Others look for what is called in German “tandem” experiences (offering their language knowledge to another person and learning from him/her the other language as a conversation). There are really good face to face courses, one of them for sure is at the Goethe Institute, either in Germany or in any premises around the world. But for those who want to start right NOW are looking for an alternative which is good and for free, Deutsche Welle offers a German course from the beginner’s level up to B1. Check it here and go for it!
