Answer:
While school is necessary to gain abundance of knowledge, there are other ways you can obtain knowledge without going to school:
- Some students learn outside of school by doing home-tuition. It is similar to school, only that you learn your subjects at home. 
- Another way is self-tutoring. You can study at home using the help of online websites, books, and advise of parents.
