How to keep a wrong answer journal

Why the journal beats redoing questions

Redoing a question you already know the answer to mostly tests your memory. Writing down the reasoning that led you astray tests the thing that actually failed. The goal is not to remember question 14. It is to recognize the shape of the trap the next time it appears under a different topic.

What to record for every miss

Keep the fields few enough that you will still do it on a tired Thursday.

• Where it came from. Test name, section, question number. This is what lets you find the question again without copying it out.
• Question type. Flaw, necessary assumption, parallel reasoning, and so on. Types are how patterns eventually surface.
• Your answer and the correct answer. Two letters. The pairing itself is informative once you have fifty of them.
• Why you chose it. One honest sentence written in the voice you had during the section, not the voice you have now that you know the answer.
• What went wrong. The specific breakdown: misread the conclusion, fell for a comparison the passage never made, ran out of time and guessed.
• The takeaway. A rule you could actually apply mid-section. "Slow down" is not one. "When a choice says 'only', check whether the passage said 'at least one'" is.

The mistake that makes most journals useless

Writing the explanation instead of the diagnosis. If your entry restates why the credited answer is correct, you have produced a second copy of an answer key. The valuable half is the account of your own reasoning: what looked appealing, what you skipped, what you assumed. That half is not available anywhere else, and it is the only part that is yours.

How often to review it

• Same day: log the misses while the reasoning is still in your head. Waiting a day turns honest recall into reconstruction.
• Weekly: read the last week of takeaways in one sitting. Ten minutes. You are looking for the sentence you have now written three times.
• Before a timed test: skim your most frequent mistake tags. Two or three of them account for most of your losses.

Turning it into a study plan

After roughly thirty entries, count them by question type and by mistake tag. The top tag is your study plan for the next two weeks. Not a broad review of everything, and not the section you find most unpleasant. Just the one failure mode that is costing you the most points, drilled until your entries stop mentioning it.

A note on copying questions

You do not need to reproduce the question text to run a good journal, and published test questions are copyrighted. Record where the question lives and what your reasoning did. When you want to reread the stimulus, open your own copy of the material.
