A practice test, for fun and training. It gauges the kind of pattern reasoning IQ tests use, but it is not a clinically validated IQ assessment. Answer at your own pace — the timer is just for interest.
Circle one answer for each question. No calculator. Untimed practice — this is a worksheet copy of the interactive test at lkforge.com/tools/quizzes/iq-test/

What this pattern-reasoning test measures
Most of what people call "IQ" on tests like this is fluid reasoning — your ability to spot a rule inside unfamiliar information and apply it, without relying on things you already know. That's exactly what these five question families probe. Number series and letter series ask you to find the hidden step and continue it. Analogies test whether you can extract a relationship and transfer it. Odd-one-out checks whether you can find the shared property four items have and the fifth breaks. And visual matrices — where a shape grows or rotates by a fixed rule — are the non-verbal, culture-fair format made famous by Raven's Progressive Matrices.
Difficulty ramps as you go: the first questions in each family are quick warm-ups, the later ones layer in geometric growth, quadratic gaps, interleaved sequences and multi-step rules. Because every test is generated fresh, you can practise the format as often as you like — and practising a format genuinely makes you faster at it, even if broad IQ itself is fairly stable.
How to read your score honestly
Your result shows a raw score out of 20, a descriptive band, and a rough IQ-scale range for reference only. Here's the honest version: a self-administered, untimed, 20-item online test cannot produce a real IQ number. Genuine IQ scores come from proctored, standardised, professionally normed batteries (like the WAIS or Stanford–Binet), and even those carry a margin of error. What this test can tell you is how sharp your pattern reasoning felt today and which puzzle types come easily to you. Use the category breakdown to find where to practise, share your score for fun, and take the band with a healthy pinch of salt.
