A credit-weighted average, in three steps
Because credits are weights, an A in a 4-credit course moves your GPA four times as much as an A in a 1-credit course. Weighted GPA adds a bonus first: +0.5 for Honors, +1.0 for AP or IB, which is how an A can count as 5.0.
Don't average your semester GPAs
Terms with more credits should count for more. Add up quality points and credits across every term, then divide once. Move the sliders to see the gap.
Rough bands on the unweighted 4.0 scale
Your band is outlined. Context matters more than the number: admissions officers weigh course rigor, and many colleges recalculate GPA using only core academic courses and their own grade values.
