IQ Test vs IQ Prep

IQ Test measures your reasoning across seven areas used by standard mixed IQ batteries: matrices and number grids, logic and letter sequences, spatial reasoning, numerical reasoning, classification, analogies, and verbal reasoning. Every sitting draws a fresh test from a bank of 424 questions in 19 different formats, so no two runs are the same. Figure questions give six answers to choose from, as progressive-matrices tests do, and the bank includes paper folding, balance scales and logic puzzles. Questions ramp from easy to genuinely hard, and the hardest ones stack several rules at once, the way real progressive-matrices tests do. Take the full 42-question test in 35 minutes, or a quick 21-question version. Everything is drawn right on your device, so the whole test works offline. SCORING THAT RESPECTS DIFFICULTY Your score is estimated with a 1-parameter logistic (Rasch) model, the same family of item-response model used by real tests. Each question sits at one of five difficulty levels, and because ability is measured against those levels rather than as a raw percentage, different random tests give comparable scores. NINETEEN QUESTION FORMATS - Figure matrices: 3x3 grids built from several parts, with rules for shape, size, shading, number and position stacked across the rows, and six answers to choose from - Number grids - Figure series and letter series - Spatial rotation of mirror-image figures, and paper folding - Number series across many rule families, shown with enough terms to pin the rule down - Balance scales: work out what weighs the same - Numerical word problems: rate, ratio, age, clock and work - Classification: figural and numerical odd-one-out - Analogies: figural, numerical and verbal - Verbal reasoning: ordering, syllogisms, if-then logic, codes and arrangements WHAT'S INSIDE - 424 unique reasoning questions across 7 categories - A different test every time: fresh, balanced, difficulty-ramped draw each run - Five difficulty tiers, from single-rule warm-ups to multi-rule matrices - Full test (42 questions, 35 minutes) and quick test (21 questions, 15 minutes) - Timer, progress bar, one question per screen, swipe or tap to move - Estimated IQ score with percentile on a normal distribution - Category breakdown across all seven reasoning types - Share your score as an image - Free: every question, your IQ, your percentile and the breakdown across all seven areas - No ads, ever - Optional one-time purchase: the full report, with every answer worked out - Fully offline. No accounts, no tracking. FREE, AND WHAT IS NOT The test is free and stays free: all 424 questions, the full 42-question sitting and the quick 21, your IQ, your percentile and the breakdown across all seven areas. There are no ads and no subscription. The full report is a one-time purchase, unlocked once and yours for every test you take afterwards. It adds every answer worked out with the rule written in plain English, your score with its 95% confidence interval, a sub-score for each of the seven areas with the range it actually pins down, your history on one chart, and a certificate. ON A WIDER SCREEN On an iPad, or an iPhone turned sideways, the test opens as two pages: the question on one, the answers on the other, the way the paper booklets it imitates are laid out.

Scores are estimates based on your answers and item difficulty, and are not a clinically administered IQ assessment.

Practise for IQ tests with the item types of real intelligence tests: matrices, number series, figure series, mirror images, operators and digit span. Plus a lab with reaction, attention and memory tasks in which you measurably improve with practice. For aptitude tests, Mensa admission and anyone who wants to know how IQ tests work. IQ TEST ITEMS • Matrices: 3×3 figure matrices as in Raven's test, up to four rules at once, and at higher levels dot patterns that combine, intersect or cancel out • Number series: 28 rule families, from simple differences to interleaved series • Figure series: rotation, count, fill, shape and movement across the grid • Mirror images: rotated or mirrored, with ever-new figures • Operators: insert the operators, precedence applies • Digit span: forwards and backwards, as in the Wechsler test Every item is generated fresh, on five difficulty levels, and after every answer you see the solution step by step. No games, no points: items look like the real test, black figures on a plain background, no animations. LAB: REACTION, ATTENTION, MEMORY Five classic tasks from cognitive psychology to practise: reaction time, Stroop, flanker, Corsi block and dual n-back. With practice you measurably improve at them; a trend curve shows your progress, plus a daily streak. Reaction, attention and memory are tested directly in some selection procedures, such as police or pilot selection. TEST UNDER REAL CONDITIONS 30 items from all categories, 20 minutes, no help until the end. Then a score per category and every wrong item with its solution to work through. SCIENTIFIC BASIS • Practice on the test format measurably improves scores. The meta-analysis by Hausknecht et al. (2007) shows gains of about a quarter of a standard deviation from retesting, more with targeted coaching. • Practising reaction and memory tasks reliably improves performance on exactly those tasks. Whether it transfers to IQ beyond them is disputed (Melby-Lervåg et al. 2016), so IQ Prep does not promise it. • The item types follow established test families: matrices after Raven, digit span after Wechsler (WAIS, WISC), number and figure series as in CogAT and similar batteries. Free to try: three items per category, one full test with mistake review, and three runs of each lab task. Full version $4.99 one time: everything unlimited.
