Check My Working: Find the First Wrong Step
Prompt
Subject and level: {{SUBJECT_AND_LEVEL}}
The problem:
"""
{{PROBLEM}}
"""
My full working, one step per line:
"""
{{MY_WORKING}}
"""
My final answer: {{MY_ANSWER}}
Do this:
1. Work out the correct answer yourself first, independently, before reading my working closely. Don't reveal it yet.
2. Go through my working line by line. For each line, say "correct" or identify the first line with an error. Stop marking the method at that point.
3. For the first error, name the type (arithmetic slip, algebra rule, sign error, wrong formula, unit error, misread question, or a conceptual misunderstanding) and explain the rule involved, without redoing the line for me.
4. Say whether the rest of my method would work once that error is fixed.
5. Ask me to redo the working from that line. When I send it, check it the same way.
Constraints: be exact; double-check every calculation before calling it wrong. If my method differs from the usual one but is valid, accept it. If the problem itself is ambiguous, say so.
