Who makes Test Merkezim?
Short answer: one person. The long answer is below — who built the site, how the test was made, and what it does and does not measure.
Why should finding an IQ test be this hard?
Search for an IQ test online and you usually run into the same three things: an email address demanded before you can see your result, a payment screen appearing on the results page, or a score with no explanation of where it came from. Test Merkezim was built to do none of those.
The 28-question test is free, asks for no account, and shows your result the moment you finish. Alongside it we added a set of brain games that work logic, memory, attention and vocabulary, plus articles on cognitive science.
Most importantly: we state plainly what the test measures and what it does not. The question structure, the scoring logic and the limitations are set out in detail on the methodology page.
Emre Karaman
Founder · Graphic designer and software developer · Born 1993Hello, I am Emre Karaman. I was born in 1993 and work as a graphic designer and software developer, involved in both the visual design and the technical build of digital products.
I started Test Merkezim to create an accessible platform where people could test their minds without paying anything or creating an account.
Where it started
Many IQ tests online ask you to pay or hand over personal details before you can see your result. I think reaching your result should be free, fast and easy. That is why Test Merkezim requires no registration and works just as comfortably on mobile as on desktop.
The platform is more than a single IQ test. With games covering logic, memory, attention, mathematics and problem solving, the aim is to keep the mind active while you enjoy yourself.
Design and development
I handle the design, the user experience and the software side myself. I use my graphic design background to build clear, uncluttered screens, and the development side to keep the platform fast and secure. I keep improving the tests, the games and the overall experience based on what users tell me.
Important note
The IQ test and brain games on Test Merkezim are intended for general information, personal curiosity and entertainment. Online test results do not replace a professional psychological assessment or a standardised test administered by a specialist. For significant decisions about health, education or development, you should consult a qualified professional.
I have written up the question structure, the scoring logic and the limitations of the test in detail on the methodology page.
You can send opinions, suggestions or bug reports to me through the contact page. Corrections get applied to the site.
