Does IQ cause more education?
At the group level, cognitive scores predict grades and attainment. Plenty of people with high scores leave school early, and plenty with average scores finish degrees. Scatter is the rule.
Does education raise IQ?
Reviews (including work in the Ritchie & Tucker-Drob line) estimate that additional schooling is associated with on the order of a few IQ points per year in some designs — with serious caveats about what “a year” means and how causal the estimate is. It is not a promise that one extra semester makes you gifted.
Why is identification hard?
Compulsory-schooling law changes, grade cutoffs, and family background all get used as levers. Each design has holes. We report the range of claims, not a fake precise number for you.
Do tests just measure school?
Verbal and knowledge-heavy tests overlap school. Nonverbal matrices still are not a culture-free destiny score. Our lite analogies and matrices are practice, not a school-leaving exam.
Is more school always better for “IQ”?
Quality, health, and opportunity matter. Years on a transcript are a crude proxy. This page is not career counseling.
Practice takeaway
Play verbal analogies and pattern matrices as school-like exercises. Correct counts stay correct counts — not a new official IQ.

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.

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 — 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.
Are Online IQ Tests Accurate? →Can You Increase Your IQ?
You can meaningfully sharpen reasoning skills, working memory, and test performance through training and education, but raising your underlying general intelligence (g) substantially and permanently is not well supported — core g is largely heritable. The honest answer is that some gains are real and some popular claims are overstated.

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.
