Your grade point average (GPA) is a weighted average of all your for-credit college work. This means a grade in a four-credit course will change your GPA more than the same grade in a three-credit course. Your GPA becomes harder to change when you take more courses. To calculate your estimated GPA, do the following:
For each course, multiply the course credit hours by the grade you receive to get the "quality points" for that course. Your grades have the following numerical equivalents: Each A is 4 points, each B is 3 points, each C is 2 points, each D is 1 point and each F is 0 points. Add up the quality points for each course. Divide the total number of quality points by the total credit hours to get your GPA for the term.
