what is a c in grades

In the United States, the letter grade C typically represents satisfactory performance, and it is usually awarded for a percentage range of 70-79% . In some schools, a C is considered the lowest passing grade, while in others, a D is the lowest passing grade. However, in college and universities, a D is considered to be an unsatisfactory passing grade, and students will usually still earn credit for the class if they get a D, but sometimes a C or better is required to count some major classes toward a degree, and sometimes a C or better is required to satisfy a prerequisite requirement for a class.
