Weighted to unweighted GPA, course by course
An aggregate weighted GPA usually cannot be converted reliably by subtracting a fixed number. Enter the courses so the worksheet can remove bonuses one grade at a time.
Calculate GPA from course evidence
The course GPA worksheet multiplies each grade-point value by its credit hours, then reports weighted and unweighted totals from the same rows.
Credits weightedDefault bonus: Honors adds 0.5; AP/IB adds 1.0; weighted points stop at 5.0. Don't treat the GPA result as official unless that policy matches the school.
Why there is no honest one-line subtraction
A weighted GPA combines grades, course credits and a school's bonus policy.
Two students with the same 4.3 weighted GPA can have different unweighted GPAs if their advanced-course mix differs. Course-level inputs preserve that missing information.
- Grade evidence
- Letter grade and its point value
- Weight evidence
- Credit hours for the course
- Rigor evidence
- Standard, Honors, AP, or IB level
The worksheet's default weighting
For GPA records, the unweighted column uses A=4, B=3, C=2, D=1 and F=0 with plus and minus values. The weighted column adds 0.5 for Honors and 1.0 for AP/IB, capped at 5.0. Your school may use different bonuses, so treat this as a planning worksheet unless its policy matches.
Credits matter
For GPA records, each grade-point value is multiplied by its course credits. The products are added and divided by total attempted credits. This prevents a half-credit elective from counting the same as a full-credit course.
Bonus points require course evidence
An advanced-course bonus belongs to a specific course, grade, and credit value.
Removing a bonus from each marked course preserves the underlying unweighted GPA evidence, while subtracting one point from the final weighted GPA does not. The worksheet therefore calculates both GPA results from the same course rows.
A reproducible weighted GPA record
A reproducible weighted GPA record lists the letter-grade table, course credits, honors or AP/IB bonus, and any cap. Four courses worth 12 total credits produce an auditable result because every quality-point product remains visible. A single weighted GPA without those inputs cannot reveal the corresponding unweighted GPA.
