Review a mistake so the next attempt is different.

An answer key tells you what was right. A useful review tells you what to do differently next time.

Locate the first wrong step

For a math question, compare your setup with the explanation before repeating the arithmetic. Did you answer the requested quantity? Did you use the same units? Did you choose the original amount for a percentage? Correct arithmetic cannot repair a wrong setup.

Use a specific error label

  • Setup: The relationship or requested quantity was wrong.
  • Calculation: The method was right, but an operation was wrong.
  • Meaning: A word or mathematical symbol was misunderstood.
  • Evidence: The reading answer added something the passage did not support.

These labels are study aids, not diagnoses. Use whichever explains the actual attempt. Avoid labeling every mistake as “careless”; that leaves you without an actionable next step.

Close the explanation and retrieve the method

After reading, cover the worked solution. Explain the first step in your own words. Then solve a new example with different numbers or a different sentence. Repeating the exact same answer immediately can test memory of the answer rather than understanding of the method.

Return after a gap

Revisit the topic in a later session. If you can explain the method and apply it to another example, move to a related skill. If you are stuck again, return to the simpler example and make the missing step explicit. The aim is reliable reasoning across different questions, not a perfect score on a memorized set.

Can you explain the method without looking?
