High average
On the standard scale (mean 100, SD 15), a score of 115 sits 1.0 standard deviation above the mean — the 84th percentile, meaning it matches or beats about 84% of the adult population. Test manuals file it under "high average" (about 16% of people).
What a score like this predicts, statistically: faster learning of novel, abstract material, and easier entry to intellectually selective paths. What it does not predict for any individual: outcomes. Within any profession, once past its entry demands, conscientiousness and accumulated expertise dominate — the tailwind is real, but modest.
Yes — 115 is comfortably above average, higher than about 84% of people. It sits in the range typical of demanding academic and professional environments.
About 1 person in 6 scores 115 or higher — it marks the 84th percentile, 1.0 standard deviation above the 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 115 as "probably between 108 and 122" from a good test — wider from a casual one. Any result quoted without an error range is overclaiming.
