    "context": "Weights mean the categories don't pull equally: raising your test average 5 points moves the course grade 2.5 points, while the same 5-point gain in homework moves it only 1 point. When you're deciding where to spend study time, always compare weight × possible gain, not the raw averages. If the weights don't sum to 100% yet (some categories still ungraded), divide the running total by the weights used so far to get your current standing.",
    "methodology": "Standard weighted mean: grade = Σ(avgᵢ × wᵢ) ÷ Σwᵢ. Category averages are simple means of the assignments inside each category unless the syllabus states otherwise (e.g., lowest score dropped).",
