What is it?

Grade Point Average (GPA) is a weighted mean of letter grades on a 0-4 scale, weighted by each course's credit hours. It's the standard summary metric used by US universities to communicate academic performance and is the gateway to scholarships, honour societies and many graduate programs.

When to use it

Computing your current GPA at the end of a term, planning what grades you need in remaining courses to hit a target, sanity-checking the figure your school's portal returns, preparing a CV or transcript.

Common mistakes

Treating GPA as a simple average of grades - it's weighted by credits, so a 4-credit A pulls more than a 1-credit A. Mixing pass/fail courses into the weighted sum (most schools exclude them from GPA). And confusing US 4.0 with the 'weighted' high-school GPA where AP/IB can push past 4.0.
