Where 124 sits on the bell curve
This score is 24 points above the average of 100, or 1.60 standard deviations. The shaded part of the curve, everyone who scores lower, covers about 94.5% of people.
What an IQ of 124 means
124 sits in the middle of the Superior range (120 to 129). It is 1.60 standard deviations above the mean of 100, so about 95 in 100 people score lower.
The Superior range runs from 120 to 129. Range names come from the Wechsler scales; they are labels for parts of the curve, not hard lines, so 123 and 125 reflect almost the same performance.
Whether 124 counts as a good IQ score depends on the comparison: against everyone, or against the people you study or work with.

- 24 points above 100, the average by definition.
- 9 points above 115, one standard deviation above average (about the 84th percentile).
- 6 points below 130, two standard deviations above average and the usual Mensa line (top 2%).
- 21 points below 145, three standard deviations above average (about 1 in 741).
How much to trust a single score
No test measures IQ exactly. Clinical tests such as the Wechsler scales report a confidence interval of roughly 5 points either side, so a measured 124 is best read as "probably between 119 and 129". Shorter online tests carry wider ranges, which is why our free test shows a 90% range next to every result.
Scores also move between sittings. Tiredness, stress and practice with the puzzle types can each shift a result by a few points, so the range name tells you more than the exact number.
