Work without time pressure
Read the question requirements until complete. You can use paper to organize steps, because the main goal is to understand how to think.
Independent practice · 10 questions · no account
Thinking clearly can be trained.
Try pattern questions, simple arithmetic, and logic. Once finished, look at the answer and the reasons. The results only state how many questions were correct in this session; results are not IQ scores, diagnoses, or measures of job aptitude.

How to use this exercise
Choose one answer per question
Questions come from Vijeron for informal practice. There are no norm banks, calibrated difficulty levels, or comparisons with the population.
Study the explanation of the answer
The correct number is useful for reviewing this session only. Repeat incorrect questions and check the reasons behind the correct answers.
02 / Interactive exercises
Ten reasoning questions
Answers are not sent to the server and are not saved. No cameras, profiles, certificates or leaderboards.
03 / Methods and limits
What do the results mean?
The score is displayed as the number of correct answers from the ten available questions. Each correct answer is worth one; no weighting, normalization, IQ estimation, percentiles, or predictions. The questions are prepared as an exercise and have not been tested for reliability, validity, language equivalency, or use with a particular group.
The performance of a single session can be influenced by experience, language, attention, device, and prior knowledge. Do not use these results for diagnosis, job selection, educational attainment, or other important decisions about a person. For formal assessments, look for professionals and tools that have evidence of validation for the purpose and user population.
The definition of standardized tests and norms can be read at APA Dictionary: standardized tests and APA Dictionary: test norm. The link is a reference to the limits of interpretation, not APA's endorsement of Vijeron's practice.

Strategy when the answer feels difficult
Look for the simplest rule
For number patterns, write the difference between the numbers first. If the difference changes, check whether there are multiplications, repetitions, or two alternating patterns.
Differentiate between “maybe” and “definitely”
In logical problems, the conclusion must apply to all circumstances that satisfy the premises. One example that refutes it is enough to show that the conclusion is not necessarily true.
Check the units and number of steps
On a practical basis, write down what is known and what is asked. Recalculating in other ways often reveals errors before choosing an answer.
