Determine which grading scale is used by your school. A four-point grading scale awards four points for an A, three points for a B, two points for a C, one point for a D, and zero points for an F. A five-point grading scale awards an additional point for honors classes. A six-point grading scale awards two additional points for Advanced Placement classes.
Calculate your current cumulative GPA. List all of the classes you have taken, along with the letter grade you earned for each class. Convert the letter grade for each class into points according to the grading scale used by your school. Average all of the grades to get your current cumulative GPA.
Earn grades higher than your calculated GPA for the remainder of your school term. For instance, if your GPA is 2.6, that is an indication that you are a B-minus student. You need to earn As and Bs to raise your GPA. A C is likely to decrease your GPA because if you calculate a two into your cumulative GPA of 2.6, it will lower your GPA.
Consider taking honors or Advanced Placement classes if your school uses a five-point or six-point grading scale. However, consider this option carefully. Honors and Advanced Placement classes are generally harder than traditional classes. Ask yourself if you are willing to put forth the required effort to perform well in honors or Advanced Placement classes.
