    "context": "A missing assignment is not the same as a low score: because categories are weighted, one zero in a heavy category can cost more than several zeros in a light one. In the example, turning in the project for even 50% lifts the course grade from 56% to 71% — a full letter and a half. Some teachers instead drop the category and renormalize the remaining weights (85×0.2 + 78×0.5 over 0.7 total weight = 80%), so check the syllabus policy before assuming the zero stands.",
    "methodology": "The math is the standard weighted-mean formula: grade = Σ(category average × category weight) ÷ Σ(weights). When a category has no submissions, most LMS platforms (Canvas, PowerSchool, Google Classroom) count it as zero unless the instructor enables a drop rule; the renormalized alternative is shown for comparison.",
