List the grade for each course and convert it to grade points using your school’s scale
Multiply each course’s grade points by the course credits (credit hours)
Add all the credit-weighted grade points together
Add all the course credits together
Divide total credit-weighted grade points by total credits
Use the resulting number as your GPA
If your school drops failing grades or uses a specific rule (e.g., only certain terms), apply that rule before totaling
If your school uses weighted GPA, use the weighting method (e.g., honors/AP/IB multipliers) before multiplying by credits
Record the GPA to the required decimal places (commonly 2 or 3)
