MCAT Mistake Log
Most mistake logs are graveyards. Yours should be a change log.
A good MCAT mistake log tells you what to change this week, not what you already got wrong. This guide covers categorization, pattern spotting, and the review cadence that turns a mistake log into an actual score gain.
- Categorize every miss as content, reasoning, or timing.
- Review the log weekly for repeats — those are your real weak spots.
- End every review with one specific change for the next week.
Format
Keep your log short enough that you will actually reread it.
The best mistake logs are simple: three columns and one weekly summary. Anything more complicated becomes a chore and gets abandoned.
- Column 1: what the question actually tested.
- Column 2: category — content, reasoning, or timing.
- Column 3: one-sentence lesson in your own words.
Categories
Content, reasoning, and timing require different fixes.
Content misses go to Anki. Reasoning misses go to a mistake pattern list. Timing misses go to your pacing rules.
- Content: I did not know this fact — make a flashcard.
- Reasoning: I knew it but chose wrong — log the trap type.
- Timing: I ran out of time or panicked — adjust pacing habits.
Miscategorizing a reasoning error as a content gap sends you back to reread material you already know.
Weekly Review
Once a week, look for repeats.
The signal is not in any one entry — it is in the patterns that appear three or more times.
- Group entries by section and category.
- Note the top 3 repeated patterns.
- Choose one to attack in the next week's practice.
Retirement
Retire lessons you have proven you learned.
A permanent log becomes noise. Retire patterns that stop appearing.
- If a pattern has not appeared in 3 weeks, retire it.
- Note retired patterns in a separate 'resolved' section.
- Reactivate any retired pattern that reappears — this is important signal.
