What Is a High School Credit?

A high school credit is a unit of measurement that shows you completed a course. When you finish a subject and pass the class, you earn credit for it. Every subject in high school gives you a certain number of credits.

1 semester course = 0.5 credit

Credits prove that you studied the required subjects and have enough knowledge to graduate.
