Our approach
Learn something useful.
Know what a result means.
IQ SpeedRun publishes educational assessments, concept guides, and free practice. We want you to understand an idea and choose your next step, whether or not you buy anything.
What the learning lab measures
Each five-question practice checks the concepts shown in its lesson. Its result is the number of those questions answered correctly. Repeating the same questions can improve familiarity; it does not establish an increase in general intelligence.
Personality and relationship practice checks knowledge and communication examples. It does not determine your personality traits, attachment style, diagnosis, compatibility, or suitability for a career.
What an assessment score means
The existing timed assessments use a limited question bank and a site-defined scoring curve. Their IQ-style numbers and percentile displays are illustrative estimates, not norms established from a representative validation study. We have not established clinical validity for these assessments.
These results cannot be used for diagnosis, school placement, employment selection, Mensa admission, or other formal eligibility decisions. Use the question-level practice and explanations to explore concepts. A professional assessment is a different process.
How we choose resources
We look for a clear connection between a resource and a lesson: spatial puzzles for reasoning, a vocabulary book for English practice, or a course syllabus for a career skill someone chooses to explore. Recommendations use the selected topic, not an inference that a low score means you need to buy something.
We write our own summaries from publisher, manufacturer and course-provider information. This selection is not a hands-on product test. We do not assign invented ratings or quote Amazon customer reviews. You can inspect the source and compare alternatives before deciding.
Affiliate links and prices
Some resource links may earn a commission when an active affiliate offer is available. A paid link is labelled nearby, and Amazon link sections identify the affiliate relationship. Earnings do not unlock practice, change your result, or determine whether you can use a learning plan.
If no approved affiliate resource fits a topic, we show the free practice instead.
Different Amazon stores have different catalogs and affiliate requirements. A store choice does not guarantee shipping to your location. We do not redirect you to Amazon automatically.
Your learning data
Practice completion and plan checkmarks stay in local browser storage. You can clear them in the learning lab. The compound calculator runs in your browser, and the amounts are not included in our analytics events.
Where site analytics is available, learning events include a topic, question identifier or completion count. Resource events identify the resource and placement. We do not add names, email addresses, practice answers or personal identifiers to Amazon tracking tags.
Authorship and corrections
Guides are published by IQ SpeedRun. We do not represent placeholder personas as credentialed experts. Tell us about a confusing explanation or incorrect source at d3vbaba@gmail.com.
