Explain it in under 80 words, plain text, using your own fall semester as the example with the math shown on one line, and end with the one thing he should take from it. No terms like 'weighted', 'quality points' or 'credit hours'. Write a prompt that gets that.","materialLabel":"His text and your grades (attached to your prompt automatically)","material":"TEXT from my brother Theo (14): wait how does college GPA work? in my school every class counts the same\n\nMY FALL SEMESTER (Riverside State)\n- Biology 101: 4 credits, grade A (4.0)\n- Calculus I: 4 credits, grade B (3.0)\n- Writing 110: 3 credits, grade A (4.0)\n- Intro to Music: 1 credit, grade C (2.0)\nTotal credits: 12.\nMath: (4x4 + 4x3 + 3x4 + 1x2) / 12 = (16 + 12 + 12 + 2) / 12 = 42/12 = 3.5\n\nNOTES\n- My first try at the math, I forgot to divide by credits and got 3.25 (just averaging the 4 grades). Wrong: 3.5 is right.\n- Point for Theo: bigger classes (more credits) count more, so a C in a 1-credit class barely hurts.\n- Theo is good at math but hates long explanations.","rules":[{"type":"maxWords","max":80},{"type":"plainText"}],"mistakes":[{"title":"Trusting the AI to count words","why":"AI is bad at counting.
