Look at this German textbook. When you start the journey to learn a foreign language, you should always consider what material you are using to learn and for what purpose. The author of this book is not from Germany. She created this course because it was very difficult for her and her family to navigate daily life in Germany. A German cannot understand this. Many courses are abstract and describe the adventures of theoretical characters. Immigrants need solutions that help them to live and raise their families in a foreign country. Imagine you bought a tool and someone gave you a manual with useful instructions: how to call your family doctor, how to buy medicine at a pharmacy, etc.
