About Letter Grades
Letter grades provide a standardized way to communicate student performance. In 1887, Mount Holyoke College became the first college to use letter grades similar to those used today, with A–E (E for failing). The letter F was introduced later as the failing grade.
There is still significant variation among institutions regarding exact percentage cutoffs and whether plus/minus grades (A+, B-) are used. The scale above reflects the most widely adopted system across US colleges and universities.
GPA (Grade Point Average) is typically calculated on a 4.0 scale. An A earns 4.0 points, and the scale decrements as grades decrease, with F earning 0.0 points.
