On the standard scale (mean 100, SD 15), a score of 103 sits essentially at the population mean — the 58th percentile, meaning it matches or beats about 58% of the adult population. Test manuals file it under "average" (about half of everyone).
Statistically, scores in this range predict typical performance on abstract, novel material — and next to nothing about any individual life. The middle of the distribution is where the scale has least to say: interests, work habits and circumstances swamp a few IQ points in every direction.
It is a solidly typical score — the range 90–109 holds about half of everyone, and everyday life, most jobs and most goals are built for exactly this range. Within it, small differences carry no practical meaning.
About 1 person in 2 scores 103 or higher — it marks the 58th percentile, essentially at the population mean.
Almost certainly, by a little. Even excellent tests carry ±3–5 points of measurement error, online tests more, and the same person swings several points between good and bad days. Read 103 as "probably between 96 and 110" from a good test — wider from a casual one. Any result quoted without an error range is overclaiming.
