Although Singapore invests huge amount of money in education, it has rather low literacy rate - 92,5%. Education is compulsory and parents who don't let their children to go to school are committing a crime. There are many teachers (24 students for a teacher in primary schools and 15 students for a teacher in secondary schools). Their educational system is highly developed.
Singapore has 4 official languages (English, Chinese-Mandarin, Malay, Tamil) which obviously influences their cosmopolitan culture.
