Two Parallel Versions (Set A / Set B) to Stop Copying
Two equal-difficulty papers (Set A and Set B) testing the same skills, each with its own key.

✅ How to use this effectively
- 1. Paste the prompt into a chat.
- 2. Fill in class, marks and chapters.
- 3. Send and read both sets.
- 4. Confirm Set A and Set B feel equal.
- 5. Print Set A and Set B alternately.
- For a trustworthy answer key: paste the finished paper into a FRESH chat and ask it to solve and grade it as an unseen exam (it catches its own slips).
🔧 If it is not right, reply with this: If one set is harder, reply: 'Set [A/B] is clearly harder than the other. Re-balance so both sets test the same skills at the same difficulty, then re-verify both keys.'
THE PROMPT
ROLE: Act as a mathematics examiner who builds matched parallel test versions.
CONTEXT: I need TWO parallel versions of the same test, Set A and Set B, for Class [CLASS/GRADE], [BOARD or EXAM e.g. CBSE / ICSE / State Board], so seat-mates cannot copy. Both sets must test the SAME skills at the SAME difficulty, with the SAME marks layout, but DIFFERENT numbers and contexts. Total marks each [TOTAL MARKS], time [TIME].
YOUR TASK:
1. Design a single skeleton (question 1 tests skill X for 2 marks, etc.).
2. Produce Set A and Set B from that skeleton, changing values and wording so answers differ.
3. Keep both sets equal in difficulty question-for-question.
4. Provide a separate answer key for Set A and for Set B.
INPUT: Chapters or topics to cover: [LIST CHAPTERS or TOPICS]. Use only these.
HOW TO WORK IT OUT: Solve every question in both sets internally, then verify each final answer twice. Confirm that matching questions in A and B are equally hard. Never invent formulas or values. Keep mathematics legible in clean LaTeX or plain text. Confirm each set totals exactly [TOTAL MARKS].
OUTPUT FORMAT, in this order:
1. HEADER for SET A: 'Mathematics Test - Set A', class, board, time, maximum marks, 'Compiled by [YOUR NAME]'.
2. SET A QUESTIONS with marks beside each.
3. HEADER for SET B: 'Mathematics Test - Set B' (same header fields).
4. SET B QUESTIONS with marks beside each.
5. ANSWER KEY - SET A.
6. ANSWER KEY - SET B.
RULES: Sets must be parallel and equally hard. Different numbers, same skills. Number every question. Each set totals exactly.
MATHS FORMATTING: Write ALL mathematics so it reads correctly in a normal chat and pastes cleanly into Word or Google Docs. Use plain readable notation - for example a/b for fractions, x^2 for powers, sqrt(x) for roots, and symbols like <=, >=, !=, +-, pi, theta, integral and sum. Do NOT output raw LaTeX or code such as \frac{}{}, \sqrt{}, x^{2}, $...$ or \( ... \) - these appear as broken symbols to a teacher in a free chat.
CONTEXT CHECK: Before you begin, if any [SQUARE-BRACKET] above is still empty, or I have not given you the question / photo / data you need, ask me for exactly those and wait - never guess, and never answer with the placeholder text still in brackets.
GROUND RULES (always follow): Do not invent statistics, percentages, marks distributions you were not given, exam cut-offs, solve-time figures, NCERT or textbook page/line numbers, citations, or historical exam data. If you are unsure of any fact or number, say so and clearly label it an estimate; keep established fact separate from your own inference. Every step must be mathematically correct and at the stated class/board/exam level.
