Can practice raise your IQ score? An honest look at the research on practice effects, plus five last-minute tips — format familiarity, sleep, time management — for performing at your true level.

'Can you raise your IQ score by practicing?' The answer: the measured score can rise a few points, but your intelligence itself doesn't suddenly increase. This article covers what practice effects really are, plus how to make sure you perform at your true level.

## What practice raises is format familiarity

Repeating the same format of problem is known to lift scores by a few points through familiarity with the question patterns (the practice effect). This isn't your intelligence rising — it's fewer points lost to first-encounter confusion. The accurate interpretation: you moved closer to your true ability.

## Tips 1 & 2: know the formats and try sample problems

For standard formats — matrix reasoning, sequences, classification — accuracy differs sharply between first-timers and those who've seen them before. Reading [the 3-step method for matrix problems](https://brainrank.jp/en/blog/matrix-tips) and [tips for number sequences](https://brainrank.jp/en/blog/number-sequence-tips), then solving a few [sample problems by domain](https://brainrank.jp/en/problems/pattern), eliminates most format-driven mistakes.

## Tips 3 & 4: sleep and time management

Sleep deprivation hits [working memory](https://brainrank.jp/en/blog/working-memory-training) directly and reliably lowers measured scores — get a full night's sleep beforehand. During the test, never fixate on one problem: give a provisional answer and move on. Most tests get harder toward the end, so points dropped early are the most wasteful.

## Tip 5: take it in one quiet sitting

Silence notifications and secure an uninterrupted environment — a broken stretch of concentration can cost you several questions' worth of points. When you're ready, measure your current level with [BrainRank's free IQ test](https://brainrank.jp/en/start) (20 questions, about 10 minutes). IRT scoring keeps lucky guesses from distorting the estimate.
