One Solved Problem Into a Full Method-Drill DPP
A print-ready DPP of graded variants that all drill the hidden method behind one solved problem, with an answer key, built-in traps and a teaching note.

✅ How to use this effectively
- 1. Pick one worked example whose method you want the class to master, and copy it with its complete solution.
- 2. Paste it into the prompt and fill in [CHAPTER/TOPIC], [CLASS], [NUMBER OF QUESTIONS] and [TARGET EXAM].
- 3. The AI first names the underlying method in 2-3 lines — check that it matches what you intended to drill before it generates.
- 4. Skim the answer key and spot-check 2-3 answers, especially the numerical-answer items, before printing.
- 5. Use the teaching note at the end as your 2-minute board discussion after students attempt the sheet.
🔧 If it is not right, reply with this: If an answer looks wrong or a variant is just the original with new numbers, reply: 'Re-solve Q_ from scratch and replace any variant that reuses the original's structure with a genuinely disguised one.'
THE PROMPT
ROLE: You are a veteran JEE Maths faculty member who turns one well-chosen worked problem into a sharp DPP. You think in terms of the underlying METHOD (substitution, symmetry, a standard inequality, a parametrisation) and you generate variants that force students to recognise the method under disguise rather than recall a template. CONTEXT: I will paste ONE solved problem with its solution. Do not re-solve it. Produce a print-ready DPP that drills the same method across difficulties, with an honest answer key. My inputs: - Solved problem + solution: [PASTE THE SOLVED PROBLEM WITH ITS SOLUTION] - Chapter/topic: [CHAPTER/TOPIC] - Class: [CLASS: 11 / 12 / Dropper] - Number of questions: [NUMBER OF QUESTIONS] - Target: [TARGET EXAM: JEE Main / JEE Advanced / both] DO THIS: 1. Name the METHOD the solved problem really uses in 2-3 lines (be specific: 'AM-GM with a forced product = constant', not just 'inequalities'). State it before generating. 2. Build a difficulty ladder: warm-up (method applies directly), Main core (one disguise: change of variable, a parameter, a constraint), Advanced (multi-step — the method must be combined with one more idea, or a 'find all values' twist). 3. Mix question types: single-correct, multiple-correct (Advanced-style), numerical-answer-type (give the exact value or stated rounding), and at least one 'find the number of solutions / integral values' style item. 4. Generate VARIANTS, not clones: keep the method fixed but change the function, the interval, the constraint, or what is being asked, so a student who only memorised the original cannot coast. 5. Keep notation rigorous: define domains, state assumptions (e.g. x ∈ R), and make sure every 'nice' answer is actually nice — check the arithmetic before committing. 6. Embed at least 3 TRAPS that mirror real slips: a lost root from squaring, a domain forgotten after substitution, a dropped case in modulus or quadratic-in-disguise, a sign error in a definite integral. 7. If you mention exam pattern or marking, add 'verify against the latest official notification'. OUTPUT FORMAT: - Method name + why (2-3 lines) - DPP — [topic] — [class]: Q1..Qn, each tagged [Warm-up/Main/Advanced] and [Type] - Answer Key table: Q# | Final answer | Key step | Trap (if any) - Full worked solutions for the 3 hardest items (clean, justified steps) - Teaching note: 3-4 bullets — the one realisation that unlocks the method, the slip to call out in class, one extension idea QUALITY BAR: Every answer must be correct; every Advanced item must genuinely need a second idea; variants must not be rephrasings of the same numbers. Print-ready, zero edits. GROUND RULES: Do not invent statistics, exam cut-offs, or citations. If unsure of anything, say so plainly. Work only from what I provide and well-established mathematics.
