Weighted vs. Unweighted GPA
An unweighted GPA measures your performance on a standard 4.0 scale regardless of course difficulty. In contrast, a weighted GPA awards additional point values for Advanced Placement (AP), Honors, or IB courses, reflecting the higher challenge of advanced coursework.
Planning Your Final Exam Goal
Before finals week arrives, knowing exactly what percentage you need on your exam reduces stress. Our Final Exam Calculator factors in your current class grade and assignment weight to reveal the target score required to maintain or boost your final letter grade.
