A GPA, or grade point average, is a number that represents a students academic achievement. It is calculated by averaging the scores of all classes taken, and is often reported on a 4.0 scale. On this scale, the top grade is an A, which equals 4.0, and the lowest grade is an F, which equals 0.0. Each letter grade corresponds to a point value, with an A worth 4 points, a B worth 3 points, a C worth 2 points, a D worth 1 point, and an F worth 0 points. Therefore, a GPA of all Bs would be a 3.0 on a 4.0 scale. However, it is important to note that some schools use a weighted GPA scale, where Advanced Placement (AP) or Honors courses are worth more than regular courses. Additionally, for admissions purposes, many colleges will recalculate student GPA so there is consistency and equity across applicants based on institutional standards and may not include all high school coursework or weights.
