Your grade point average (GPA) plays an important role during your school years. At the high school level, your GPA determines what scholarships you may win or what colleges or universities might accept you. At the college level you often need to maintain a minimum GPA to avoid probation or expulsion and your GPA will affect which graduate schools or jobs that you can get after graduation.
Request your transcript from your counseling office and check the school's formula for weighting grades, if any. Most colleges do not weight grades. Some high schools do, while others opt to use unweighted grades.
Translate each letter grade into the number of points it is worth. Typically As are worth four points and each lower grade goes down by one point. A plus often adds 0.3 points, while a minus subtracts 0.3 points. For example, a B+ would be worth 3.3 while a B- would be worth 2.7.
Multiply the points equivalent to your letter grade by the credits each class is worth to find the points earned for the class. For example, for a B+ in a five-credit course, multiply 3.3 by 5 to get 16.5.
Add the points earned in each class together to find your total points earned. You can use all of your classes to find your overall GPA, classes in your major or classes taken in a particular term.
Divide your total points earned by the credits taken in the specified period (overall, your major, or your term) to find your GPA. Finishing the example, if you earned 202 points over 56 credits, divide 202 by 56 to get a GPA of 3.61.
