A mock test is not an exam. It is a diagnostic that happens to look like one, and treating it purely as a score is discarding most of what it produces.
Sit it properly or do not sit it
Full duration. No pauses. No checking a textbook for "just one". No phone. The point is to reproduce the conditions in which your judgement will actually be tested, and a mock taken with three interruptions measures something else entirely.
That includes the time of day, where you can manage it. A brain at 2pm behaves differently from a brain at 10pm.
Classify every question before you look at the answers
Immediately afterwards, go through and mark each one:
- Knew it — answered with confidence.
- Worked it out — derived it, took time.
- Narrowed and guessed — eliminated, then chose.
- Blind guess — no information.
- Skipped — left blank deliberately.
Do this before seeing the key, or hindsight rewrites your memory of how confident you were.
Now compare against the key, and read the four cells
| You thought | Result | What it means |
|---|---|---|
| Knew it | Wrong | The most important category. A confident error is a belief you will repeat until something corrects it. |
| Guessed | Right | Not a mark you own. Learn the topic before it reappears. |
| Worked it out | Right, slowly | Solid, but check whether the time was affordable. |
| Skipped | — | Was it genuinely unknown, or did you run out of time? Different problems, different fixes. |
Confident errors are the whole point
A question you knew you did not know costs you four marks. A question you were sure about and got wrong costs you five — and, worse, it will cost you again, because nothing in your preparation has flagged it.
Those are the questions to write down, with the reason, and revisit.
Check where the time went
If a section ran long, find out whether it was many questions each slightly slow, or two questions that ate nine minutes. The first is a fluency problem and improves with practice. The second is a decision problem and improves with a rule: if I have not seen the route in ninety seconds, I flag it.
One mock, analysed, beats three taken and forgotten
The analysis is slower than the test. That is the correct ratio — and it is the part almost everyone skips, which is why mock scores plateau.
