Can you actually increase your IQ?
You can improve your measured performance and some specific skills, but large, permanent jumps in core intelligence are unlikely. Fluid intelligence (Gf) can shift modestly with sustained working-memory and reasoning practice, and more education reliably raises scores by a few points. However, general intelligence (g) is substantially heritable, so the realistic goal is to reach and maintain your potential, not to add 30 points.
Does brain training really work?
Brain-training games mostly make you better at those specific games, with limited transfer to general intelligence. Research shows practice improves the trained task and sometimes closely related skills, but the evidence for broad, lasting IQ gains is weak. Working-memory training can produce small short-term improvements in fluid reasoning, though these effects tend to fade without continued practice.
What lifestyle factors support cognitive performance?
Good sleep, regular exercise, reading, and learning new skills all help you perform at your cognitive best. Sleep consolidates memory and restores attention, aerobic exercise supports brain health, and continual learning builds knowledge (crystallized intelligence) over a lifetime. These habits won't turn an average score into a gifted one, but they protect and maximize the ability you have.
What's the difference between fluid and crystallized intelligence?
Fluid intelligence (Gf) is your ability to reason and solve novel problems, while crystallized intelligence (Gc) is accumulated knowledge and skills. Gf tends to peak in early adulthood and is harder to change, whereas Gc keeps growing for decades through reading, education, and experience. Many lifelong learning gains show up in crystallized intelligence, which is why staying mentally active pays off over time.
How can I do better on an IQ test specifically?
You can raise an IQ-test score modestly by getting familiar with the question types, sleeping well, and staying calm and focused during the test. Practicing pattern-recognition puzzles like matrices reduces the 'novelty penalty' of unfamiliar formats, which is a real effect. Just remember this improves your test score, not necessarily your underlying intelligence, so treat any single result as an estimate.

What Is a Good IQ Score?
An IQ of 100 is exactly average; 110-119 is above average, 120 and up puts you in the top 10% (a genuinely 'good' score), and 130+ is considered gifted. IQ is built on a normal distribution with a mean of 100 and a standard deviation of 15, so most people cluster near the middle.
What Is a Good IQ Score? βIQ Percentile Chart: What Percentile Is My IQ?
Your IQ percentile tells you the share of people you scored higher than: an IQ of 100 is the 50th percentile, 115 is about the 84th, 120 is roughly the top 10%, and 130 is roughly the top 2%. The table below maps every major IQ band to its classification, percentile, and share of the population.

A well-designed online IQ test gives a reliable estimate of your reasoning ability, but it is not a clinical diagnosis β only a proctored test like the WAIS or Stanford-Binet provides that. This test is built on Raven's Progressive Matrices and CHC theory, scored on the standard scale (mean 100, SD 15), with an internal reliability (Cronbach's alpha) of about 0.85-0.92.

A 'genius' IQ traditionally starts at 140, while 130 and above is labeled 'very superior' on modern tests. Scores that high are extremely rare, and the famous IQ numbers you see for historical figures are almost always estimates, not measured results.

The average IQ is 100 at every single age, from children to seniors, because IQ tests are age-normed to your own age group. 'Average IQ by age' charts that show rising or falling numbers are misleading, since the scoring is recalibrated for each age band.
