Grade (education)

Grades

are a teacher's evaluation of a student's performance. They are often letters (e.g. A, B, C, D, F,) or numbers (e.g. 1-10.), although in some countries they do not use either of these systems.

Letter grades are most commonly used in the United States and some others. The grades D or C are usually enough to pass.

Grades can also be on a number scale. Typically a midpoint score is a pass. Sometimes the numbers can go in descending order to indicate better performance.

A Grade Point Average, or GPA, takes the grade(s) of a student and assigns point values to them. These points are added up and divided to calculate the GPA.

Simple grades can be found with this formula:

[math]\displaystyle{ \frac{\text{right}}{\text{right}+\text{wrong}} }[/math]

The grade is the answer to that formula turned into a percent.

This is the type of grading the United States commonly uses.:

93%-96%	A
90%-92%	A-
