A practice test, not a clinical assessment: the questions are original and the score isn't normed on a population sample, so treat it as a rough estimate. What real IQ tests measure.
How the estimate works: this test isn't normed, so we assume an average adult answers about half the questions right (15 of 30) and that each 5 questions is roughly one standard deviation (15 points), then cap the estimate between 70 and 145. Real IQ scores come only from standardized, normed tests. What a score actually means.
Your IQ is one input. How you decide matters more.
