Your high school grade point average may be important for getting into the college of your choice or receiving a scholarship. Figure out your GPA by gathering your transcripts, then doing the math. You can use this method to determine your GPA for a semester or your entire high school career.
Write down the grade you received or expect to receive in each of your classes. Alongside it, place the number associated with the grade.
Check to see how your school assigns points for plus and minus grades. A common point system uses the following values: A = 4, A- = 3.67, B+ = 3.33, B = 3, B- = 2.67, C+ = 2, C- = 1.67, D+ = 1.33, D = 1, D- = .67, F = 0.
Add up the numbers to find the total earned for all of your grades. Divide this by the number of grades on your list. This is your grade point average.
