Academic grading in the United States

The typical grades awarded for participation in a course are (from highest to lowest) A, B, C, D, and F. Variations on the traditional five-grade system allow for awarding A+, A, A- ; B+, B, & B-; C+, C, & C-; D+, D, & D-; and F. In primary and secondary schools, a D is usually the lowest passing grade, however, there are some schools that consider a C the lowest passing grade, so the general standard is that anything below a 60 or 70 is failing, depending on the grading scale. In college and universities, a D is considered to be an unsatisfactory passing grade. 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.
