No ones really sure, at least to my knowledge. She did not go to regular school, but she was taught at home because her mother didn't believe in schools. Good luck!
Agatha Christie did not go to college. Her mother did not believe in schools instead she was home schooled and had some tutors. She had a french tutor/nanny who only spoke in french.
Agatha did not attend school. Her mother believed that education destroyed the brain and ruined the eyes. Her mother taught her history and something called "general knowledge."Agatha read newspapers...
No-one knows. She went missing from her home in Berkshire, leaving a note saying that she was going to Yorkshire. She was found in Yorkshire eleven days later, in a hotel in Harrogate.
