Frequently asked questions

How do I calculate my semester GPA with plus/minus grades?>
Enter each course's letter grade (including plus/minus like B+ or A-) and its credit hours. The tool maps each grade to GPA points — B+ is 3.3, A- is 3.7, etc. — multiplies by credits, and divides total points by total credits.
What GPA do I need to get off academic probation?>
Most schools require a 2.0 cumulative GPA to exit academic probation, but policies vary. Use this calculator to find out what grades you need this semester to bring your cumulative GPA above your school's threshold.
Does a course with more credit hours affect GPA more than a 1-credit course?>
Yes. GPA is credit-weighted, so a 4-credit course with an F has a much bigger negative impact than a 1-credit A. This calculator accounts for that automatically.
Can I use this to calculate my cumulative GPA across multiple semesters?>
Yes — just add all your courses from every semester into the rows. The calculator will weight them all together by credit hours, giving you an accurate cumulative GPA.
