Tag each course as Regular, Honors, AP or IB and see your weighted GPA on the 5.0 scale — plus your plain unweighted GPA side by side, since most colleges recalculate it that way.
Pick a letter grade for at least one course to see your weighted GPA.
Weighted scales add points to grades earned in advanced courses. The most common scheme adds +1.0 for AP, IB and dual credit and +0.5 for Honors, so an A in AP Chemistry is worth 5.0 instead of 4.0:
weighted value = unweighted grade value + course boost Regular: +0.0 (4.0 scale, max 4.0) Honors: +0.5 (max 4.5) AP / IB: +1.0 (5.0 scale, max 5.0)
Schools differ — some weight by percentage points instead, and some cap how many weighted courses count. This calculator uses the common +0.5/+1.0 scheme; if your school publishes its own scale, plug those values in manually by picking the closest level.
