SAT Error Log: Turn Mistakes Into Practice

An SAT error log is a record of why you missed a practice question and what you will do differently next time. It should capture your reasoning, not just the correct answer. Use official practice to assess performance and targeted review to work on the underlying skill.

College Board provides official practice through Bluebook and directs students toward its Student Question Bank for further work on skills. Check its current guidance for how to use those resources. The template and example below are independent study aids, not official SAT content or a score-conversion method.

Copy this error log

Avoid filling the log with full question text. A reference and a short description of your reasoning are usually enough. Follow the provider's terms when handling its materials, and keep answer keys out of view until after an attempt.

Classify the mistake before choosing a drill

A concept error means a definition or relationship is unclear. A setup error means you know the ingredients but built the wrong equation or interpretation. An execution error includes arithmetic or transcription slips. A reading error can come from overlooking a qualifier. Timing can be a separate issue or the consequence of uncertainty about the method.

These labels are useful only if they change your next action. More timed questions may not fix a missing concept. Rereading an explanation may not fix a habit of copying a number incorrectly. Start with the earliest decision in your reasoning that went wrong.

Work an original example

Consider this practice question: a fictional item costs 80 units and its price increases by 25 percent. What is the new price? This is an original illustration, not an SAT question. The increase is 20, so the new price is 100.

If you answered 105, the likely issue is treating the percentage as a fixed amount. Write the calculation as 80 plus one quarter of 80. Now try a different starting price and explain what the percentage is relative to. If you answered 20, you may have calculated the increase correctly but missed that the question asks for the new price.

Those two mistakes need different corrections even though both final answers are wrong. Ask an AI tutor for another clearly labeled concept exercise and check the arithmetic yourself before relying on it.

Decide what happens at the next session

For a concept gap, explain the rule and solve a simple fresh example. For a setup problem, state the relationship in words before calculating. For an execution slip, identify a check that would catch it. For a timing concern, first establish whether you can solve the task independently without a clock.

Return to official practice covering the skill when you are ready. A good result on a generated drill does not establish an official score or percentile. Do not infer a guaranteed score gain from completing an error log.
