The 4.0 scale
Each letter grade is worth a number of points: A and A+ 4.0, A− 3.7, B+ 3.3, B 3.0, B− 2.7, C+ 2.3, C 2.0, C− 1.7, D+ 1.3, D 1.0, D− 0.7 and F 0. Each course's points are multiplied by its credits, the products are added up, and the total is divided by the number of credits. So an A in a 4-credit class moves your GPA more than an A in a 1-credit one. Some schools give an A+ 4.3; switch on A+ counts as 4.3 if yours does.
Weighted and unweighted
The unweighted GPA uses the points above for every class. The weighted GPA adds 0.5 for an Honors class and 1.0 for an AP or IB class, so an A in AP Biology counts as 5.0. An F gets no extra points, at any level. Schools weight in different ways, and many colleges recalculate GPAs their own way, so check your school's handbook for the exact rule.
Adding a term to your GPA so far
Open Add to your GPA so far and put in the cumulative GPA and credits from your transcript. Your new cumulative GPA is the grade points you already had (GPA times credits) plus this term's, divided by all the credits together: a 3.0 over 30 credits plus a 3.5 over 6 makes 3.08. Use the same kind of GPA you put in; if your transcript's GPA is weighted, read the weighted figure.
Questions
Do courses without a grade count?
No. A row with no grade picked, or with 0 credits, is left out, so you can leave empty rows in place or use 0 credits for a pass/fail class that does not count toward GPA.
What if my school uses percentages?
Turn each percentage into the letter grade your school gives it, then pick that letter. A common US scale is 93 and up for an A, 90 to 92 for an A−, 87 to 89 for a B+, and so on down in steps of about 3, but schools differ, so use the scale on your syllabus.
Is anything saved?
No. Your courses and grades are worked out in this page and are gone when you close it.
