Prepare by learning the formats, reading the instructions and planning your time. Practice can improve familiarity; a higher repeat score does not by itself show a change in general intelligence.
The routine, in order
- Learn the item formats. Try examples of matrix reasoning, number series, verbal analogies and spatial rotation. Follow the rules of any formal assessment about preparation.
- Keep a regular sleep routine. Plan enough time to rest before testing. There is no guaranteed score gain from a particular number of nights.
- Take one full timed practice test. A timed practice run can help you understand the controls and plan your pacing. It does not validate the resulting score.
- Plan your skip strategy. Decide in advance how long you will give a single question before moving on. Roughly 90 seconds is a reasonable ceiling on a 25-question timed test.
- Set up the room. Quiet, warm, phone in another room, no interruptions for the full window. Test conditions affect scores measurably and this is the easiest variable to control.
Why format familiarity works
The first time you meet a matrix reasoning item, part of your effort goes into working out what is being asked. The grid changes along two dimensions at once, one option breaks a rule the others obey, and none of that is explained. Once the format is familiar, that overhead disappears and the whole 90 seconds goes to the actual problem.
Repeated exposure can change performance through familiarity or remembering answers. A higher second score is not necessarily a more accurate estimate of ability. Follow the instrument's retesting guidance for a formal assessment.
Try matrix completion, number series, verbal analogy and mental rotation examples. Review unfamiliar instructions before adding time pressure; no fixed practice duration guarantees readiness.
Plan time to rest
Fatigue can make sustained attention and careful work harder. Avoid scheduling a practice session when you are exhausted; we cannot predict a score change from sleep alone.
Keep a regular sleep routine rather than relying on a last-minute change. Preparation should fit your usual needs and any professional advice you receive.
Avoid experimenting with unfamiliar stimulants or abrupt changes to your usual routine on test day.
Make room for a calm start
Test anxiety measurably suppresses scores, and it does so through working memory: worry occupies the same limited resource the test is trying to measure. Someone anxious enough is effectively taking the test with less capacity available.
Allow setup time and read the instructions before starting. A brief pause or slow breathing may help you settle; it does not guarantee better performance.
Reframing helps too, and there is decent evidence for it. Interpreting the physical signs of arousal as readiness rather than as fear changes performance, because the sensations are largely the same and the interpretation is the part you control.
Pacing and the skip decision
On a 25-question timed test, the most common way to lose points is spending six minutes on one hard item and then rushing five easy ones at the end. Every question is worth the same. A hard one is worth no more than an easy one you did not reach.
Set a ceiling before you start. Around 90 seconds per question is sensible on a 25-minute test. When you hit the ceiling, take your best guess and move. If the test lets you skip and return, use it; if unanswered items are scored as wrong, always guess rather than leaving a blank.
On multiple choice, eliminate before you select. Removing two implausible options doubles the value of a guess, and on sequence items the wrong answers are frequently constructed from the near-miss rules, so identifying why an option is wrong often reveals the right rule.
What does not work
Improvement on a practised task does not by itself demonstrate improvement in general intelligence. Evaluate learning by what you can explain and apply to a new problem.
The existing timed assessments use a limited question bank and a site-defined scoring curve. Their IQ-style numbers and percentile displays are illustrative estimates, not norms established from a representative validation study. We have not established clinical validity for these assessments.
Cramming general knowledge does not help on fluid reasoning items, which are designed to require no prior knowledge. It does help slightly on vocabulary items, but vocabulary accumulates over years of reading and a week of word lists produces recognition without any sense of how the words are used.
Questions people also ask
How much can practice raise an IQ score?
The effect depends on the task, the interval and prior exposure. Remembering items or learning the format can raise a repeat score without establishing a change in general intelligence.
Should I practice the day before or a week before?
Spread practice into manageable sessions and leave time to rest. Review explanations rather than repeatedly chasing a higher score on the same items.
