Yes, a 4.7 GPA is entirely possible on a weighted grading scale, which is typically utilized by high schools that offer advanced coursework such as Honors, Advanced Placement (AP), or International Baccalaureate (IB) classes. Because weighted scales award extra grade points for rigorous classes—often giving a 5.0 for an A instead of the standard 4.0—students who consistently challenge themselves with high-level academic classes and earn top marks can push their cumulative weighted GPA well past the standard unweighted maximum, sometimes reaching ceilings of 4.6, 4.7, or even higher depending on the specific weighting formula used by their school district.
