Frequently asked questions

What does this IQ Test measure and who is it for?

It measures reasoning across logic, sequence patterns, geometry and numerical problems. It suits learners or curious readers who want to practise cognitive ability, and people preparing for exams that involve similar mental challenges.

What are the available formats and levels, and which one should I choose?

There are Easy, Intermediate and Expert levels, each in a Short version of 10 questions for about 5 minutes or a Full version of 30 questions for 13 to 15 minutes. Choose Short for a quick overview; Full gives a more precise score.

How should I prepare for this specific reasoning test?

Practise recognising number and shape sequences, mental rotation, mirror reflection and formal logic statements. Work through problems untimed first, then repeat under the same countdown pressure. Revise percentage changes, set logic and counting methods.

How do I read my score, band and certificate after finishing?

Your result shows the number of correct answers. Bands are Needs work below 40%, Intermediate from 40%, Advanced from 60% and Expert from 80% only at Expert level; other levels top out at Advanced. A pass earns a PDF certificate with score, date, certificate number and QR code.

Can I take this test again, and does it measure memory?

Yes. Use 'Start again' as often as you want. The questions are the same and in the same order, so a retake mostly measures memory rather than fresh reasoning.

What appears in 'The rankings', and which attempt counts?

Rankings can be filtered by test, country and city. They show only first name, last-name initial, country, city, score and time. Only your best attempt counts: highest score, then shortest time.

Is my result visible to others, and can I delete my data?

A result is visible only to the person who took the test. You can request deletion of your personal data from the site's data rights page; it is a request, not an instant button.

About this test

Identifying logic within sequential patterns

Cognitive ability often manifests in the way you perceive order within a seemingly chaotic series of data. In daily life, this skill helps you predict trends or anticipate the next step in a complex project. The IQ Test focuses heavily on numerical sequences where the progression follows a specific mathematical rule.

Logic is not restricted to numbers alone. The evaluation includes tasks related to formal deductive reasoning and set theory. You will need to consider the logical implications between different categories and determine what is necessarily true based on a given statement. In a professional setting, this mirrors the way you might interpret a contract or follow a chain of command.

Analysing spatial transformations and symmetry

Spatial reasoning is a fundamental component of this evaluation, reflecting how you interact with the physical environment. Whether you are navigating a new city or following a complex diagram, the ability to mentally manipulate objects is essential. The IQ Test presents figures that undergo specific movements, such as a quarter-turn or a half-turn.

Axial symmetry and mirror reflections add another layer of complexity to these visual puzzles. Instead of a simple rotation, you must imagine a figure flipped across a horizontal or vertical axis. These tasks require you to perceive how the orientation of individual elements changes when reflected.

Deciphering matrices and multi-rule systems

The matrix reasoning section uses a three-by-three grid to test your ability to synthesise multiple rules at once. To find the missing cell, you must look at both rows and columns simultaneously. Solving these grids requires identifying how different characteristics, such as the type of figure, the quantity of elements, or the rotation of a shape, change across the grid.

Beyond shapes, the IQ Test delves into practical mathematics and likelihood. You will face challenges involving mixtures and compound percentages, which are common in retail or finance. Calculating a net change after successive shifts or determining the final composition of combined substances tests your grasp of proportions.

Probability and deductive syllogisms

Advanced reasoning involves understanding the likelihood of events and the strict rules of formal logic. You will apply principles of classical probability to outcomes, such as those involving fair dice, to determine the chance of a specific result. Additionally, the test uses set logic to calculate totals within overlapping groups, requiring you to account for individuals who belong to multiple categories.

The evaluation also includes syllogistic logic and combinatorics. You might be asked to determine the number of unique interactions, such as handshakes, within a group of people. Other questions present logical premises about groups of animals or objects, requiring you to identify which statements are logically certain based on the provided rules. These challenges ensure a balanced assessment of both your mathematical intuition and your deductive rigor.

Choosing between the short and full evaluation

This assessment is designed to fit different schedules while providing a consistent challenge. If you are looking for a quick mental workout, the short version offers 10 questions to be completed in 5 minutes. This condensed format focuses on core skills like basic sequences and simple rotations, providing a rapid snapshot of your reasoning speed.

For a more comprehensive analysis, the full version consists of 30 questions with a duration of 14 minutes. This longer format allows for a broader range of topics, including intricate matrices, volumetric changes, and complex syllogisms. Upon completion, your results will reflect your performance across the distinct categories of matrices, sequences, rotations, and analogies. You can use this feedback to identify which areas of reasoning are your strongest.
