The six causes behind every wrong answer
Every miss has a cause. Tag it with one of these, and your review stops being a pile of questions and starts being a short list of fixable habits.
Conceptual
You did not know the underlying rule or method. The fix is learning, not speed.
Careless
You knew it but slipped — a sign error, a misread digit, a skipped step.
Time Pressure
You rushed because the clock was tight, and accuracy paid for it.
Misread
You answered a slightly different question than the one on the screen.
Strategy
The math was fine but the approach was slow or roundabout — a better path existed.
Other
Anything that does not fit cleanly above. Tag it, then refine as patterns emerge.
How to use it
- 1After every practice set or mock, open the template and add one row per question you got wrong or guessed.
- 2Tag each mistake with one of the six causes below. Be honest — the tag is the whole point.
- 3Write one line on what actually went wrong and what you will do differently.
- 4Once a week, sort by tag. The biggest bucket is your highest-leverage thing to fix next.

Common questions
Yes. Enter your email and the spreadsheet downloads immediately — no account, no card. If you opt in, you will also get a short series on how to actually use the log, which you can unsubscribe from in one click.
No. The template is a standalone spreadsheet that works on its own. The full platform has the same six-tag error log built in (plus spaced review of your mistakes), and every new account starts with a free 7-day full-access trial if you want it.
Volume alone repeats the same mistakes. Logging and tagging turns each miss into a pattern you can see — and patterns are what you fix. It is the single habit that moved Adam's score the most, though no method can promise any specific result.
Yes. The tags describe why you missed a question, which is the same across Quant, Verbal, and Data Insights on the Focus Edition.
