Writing quiz questions with plausible wrong answers can take longer than teaching the lesson. This skill writes questions across recall, understanding and application, with wrong options based on real misconceptions rather than obvious throwaways, and no 'all of the above'. Each question comes with an answer key, a one-line explanation and a difficulty tag. When you paste source text, questions come only from it, so the quiz matches what you actually taught. To use it, paste the skill into your assistant and send the topic or source text, level, number and type of questions; the reply is laid out as “Questions”, “Answer key with explanations” and “Difficulty tags”.

ProblemOne worksheet can't fit a class with very different levels.
Grade 5 maths, adding fractions with unlike denominators, 8 questions
Support: worked example 1/2 + 1/3 = 3/6 + 2/6 = 5/6, then 4 similar questions.
Core: 8 mixed questions including word problems.
Challenge: 'Find two fractions with different denominators that add up to 1.'
Immediate resultThe same worksheet at three levels — support, core and challenge — with an answer key.
ProblemWriting personal, useful feedback on 40 assignments is exhausting, so feedback gets generic.
Class 8 paragraph on climate change; rubric: claim, evidence, clarity
What's working: your opening claim is clear — 'Cities are getting hotter every summer.'
Improve: back it with one fact, such as a temperature record from your city.
Next step: find one news source and add a sentence that starts 'According to…'.
Immediate resultSpecific feedback for a piece of work: what's working, one thing to improve and a next step.
ProblemCourses grow topic by topic without clear outcomes, so learners finish without new skills.
6-hour course: Excel for new finance hires
Outcome: build a monthly expense report with SUMIFS and a pivot table without help.
Module 3 (75 min): lookups — XLOOKUP · activity: match invoices to vendors
Final project: reconcile a month of sample transactions.
Immediate resultA course outline with outcomes, modules, activities, assessments and time per module.
