Where does Scout receive the majority of her education?

Scout gets most of her education at home.  Atticus teaches her to read.  Scout can't remember a time when she couldn't read, and reading is important to her.  When Scout goes to school, her teacher, Miss Caroline, is very upset that Scout is so far ahead of the rest of the students.  After all, how is Miss Caroline going to teach everyone to read BUT Scout?  Scout, in turn, does not respond at all well to the methods Miss Caroline is using to teach the class.  Atticus basically tells Scout they will keep reading together if she agrees to behave at school, which she does.
