How to review a practice test: keep an error log

Checked against official sources on 22 September 2026.

A full-length practice test takes two or three hours. Most of its value comes in the hour after it, when you work out why each point was lost.

Log every question you did not get cleanly

That means every wrong answer, every skipped question, every guess that happened to be right, and every question that took much longer than it should have. For each one, write down:

1. The question number and its topic or skill.
2. What you answered, and the correct answer.
3. Why it went wrong: a gap in content, a misread, a careless slip, or time pressure.
4. What you will do about it: a rule to learn, a method to practise, or a pacing change.

Redo before you read

Attempt each missed question again without a timer before reading the explanation. If you get it right untimed, the problem was speed or focus; if you still cannot, it is a content gap.

Let the pattern set the plan

After two or three tests, the log shows which causes dominate. A cluster of content gaps in one skill calls for targeted question-bank practice on that skill; a cluster of time losses calls for timed sets.
