In college, a student may take several courses. for each course i, he earns a certain credit (ci
), and a mark ranging from A to F, which is comparable to a score (si
), according to the following conversion table
The GPA is the weighted average score of all courses one student may take, if we treat the credit as the weight. In other words,
An additional treatment is taken for special cases. Some courses are based on “Pass/Not pass” policy, where stude nts earn a mark “P” for “Pass” and a mark “N” for “Not pass”. Such courses are not supposed to be considered in computation. These special courses must be ignored for computing the correct GPA.
Specially, if a student’s credit in GPA computation is 0, his/her GPA will be “0.00”.
