At the start of education, there are preschool and kindergarten, where children acquire early skills, followed by elementary grades (K-5), where children learn reading, mathematics, and basic sciences. The middle schools (6-8) continue to prepare students with preparations at a higher level, whereas the high schools (9-12) give the students basic academics, career orientation, and also advanced programs such as honors and AP classes.
