Question: what is the difference between high school and middle school?
Answer: It means lower primary (1–5), upper primary (6–10). From class 6–8 is thought of as middle school. Grades 1,2,3,4 and 5 are said to be primary school while all the classes from 6 to 10 are considered high school (as middle school and high school are not considered separate) while 11–12 (inclusive) is called college.
