    "context": "Drop policies change the math significantly: dropping the lowest score raised the average 2.5 points in the example, which is why 'drop one test' syllabi are so valuable. If your tests have different point values rather than explicit weights, use the points method instead — total earned ÷ total possible — which weights each test by its length automatically.",
