FAQ
What is the highest GPA?
Unweighted scales cap at 4.0 for straight top grades; weighted scales can go higher.
Unweighted vs weighted
On a common unweighted 4.0 scale, the maximum is 4.0 (often with A and A+ both mapping to 4.0).
Weighted high-school GPAs may reach 5.0 or more when AP/IB/Honors courses carry extra points—again, follow your school’s published rules.
