Grading systems by country
North America
At most schools, colleges and universities in the United States, letter grades follow a five-point system, using the letters A, B, C, D and E/F, with A indicating excellent, C indicating average and F indicating failing. Additionally, most schools calculate a student's grade point average (GPA) by assigning each letter grade a number and averaging those numerical values. Generally, American schools equate an A with a numerical value of 4.0. Most graduate schools require a 3.0 (B) average to take a degree, with C or C− being the lowest grade for course credit. Most undergraduate schools require a 2.0, or C average to obtain a degree with a minimum of D or D− to pass a course. For most secondary schools, the minimum overall and course passes are both D or D−. Some districts, such as Mount Olive Township School District in New Jersey, have eliminated D as a passing grade for their students due to a high failure rate.
