Until very recently, Margret was illiterate. Margret went back to school just a few years ago, at an adult education center and even though she had never learned to read or write, she quickly became the center's top student. The center was so impressed that they decided to offer Margaret a teaching job. But books are scarce and expensive where Margaret lives. That's why she uses Worldreader on her mobile phone to teach her students, to read and to read with her own children.
