Many high scorers say the same thing about what changed their prep: they kept track of their mistakes. Not a vague feeling of having studied them, but a written record they could go back to. A wrong-answer journal is simple, cheap, and one of the most commonly recommended study tools.
Most students never build one, because it sounds like homework. The trick is to make it small enough that you will keep doing it. This guide gives you a format, an example, and a weekly routine.
A single miss tells you very little. Fifty misses, written down, tell you a lot. The journal lets you see patterns you cannot see in the moment: that you keep missing the same type of question, that you keep falling for the same type of trap, or that your errors come from rushing and not from not knowing.
It also forces a useful habit. To write why you got something wrong, you have to understand it, and understanding is where the learning happens.
Keep each entry short. These five fields are enough:
| Field | Example |
|---|---|
| Test and question | PT 112, Section 2, Q14 |
| Question type | Weaken |
| Why I picked my answer | It sounded relevant and used the same words as the stimulus |
| Why the right answer is right | It attacked the link between the evidence and the conclusion |
| Cause (pick one) | Content gap / Execution / Timing / Unlucky guess |
Add one extra line if you can: a rule for next time. For example, “Check that the answer addresses the conclusion, not just the topic.” Over time those rules become your personal checklist.
The cause field is the most useful part of the journal. It matches the four buckets we describe in what to do after a bad practice test:
| Cause | What it means | What to do |
|---|---|---|
| Content gap | You did not know the concept or rule | Study that question type |
| Execution | You knew it but misread or rushed | Slow down on the first pass, use a short checklist |
| Timing | You ran out of time and guessed | Work on pacing and triage |
| Unlucky guess | You narrowed it down and guessed wrong | Nothing, move on |
If your journal shows mostly timing misses, more content study is less likely to help. If it shows mostly content gaps, more pacing drills are less likely to help. The journal tells you which kind of help you actually need.
Some students find that writing by hand helps them remember. Others prefer a spreadsheet because they can sort and count. Either works, as long as you actually use it. If you type, keep the columns above. If you handwrite, keep a notebook with the same fields and tally up the causes at the end of each week.
The journal only pays off if you read it. Once a week, spend fifteen minutes on three things:
1. Count by cause. Which of the four is biggest?
2. Count by question type. Where do the same types keep appearing?
3. Pick one fix. One adjustment to make this week, not five.
When the same question type shows up repeatedly, go to the relevant guide and study it directly. For example, if Strengthen and Weaken questions keep appearing in your log, that is where your next study hour should go.
The journal works best alongside blind review. After a test, redo the questions you flagged as uncertain without looking at the answers. Questions you get right on the second try but missed under time pressure are usually execution or timing problems. Questions you still get wrong are usually content gaps. Both go in the journal.
A journal is also the best tool for breaking through a stall. Looking back over weeks of entries often shows a pattern you never noticed. If your scores have flattened, read the LSAT plateau and then go through your journal with those questions in mind.
