What an IQ of 105 means
A score of 105 places you above 63.1% of the population on the standard scale. Here is what that means in practice, the margin of error it carries, and how many people in our own sample scored there.

Where 105 falls on the curve
The marker shows the position and the band shows the margin of error. No test returns an exact point: an 105 strictly means “between 94 and 116 with 95% confidence”. That is why retaking the test another day and scoring a few points apart is not a contradiction — it is ordinary measurement noise.
Compared with neighbouring scores
Five IQ points sound like little and move the percentile far more than people expect. Here is how:
| IQ | Percentile | Classification |
|---|---|---|
| 95 | 36.9% | Average |
| 100 | 50% | Average |
| 105 | 63.1% | Average |
| 110 | 74.8% | High average |
| 115 | 84.1% | High average |
Frequently asked questions
Is an IQ of 105 good?+
“Good” depends on what for. Statistically, 105 places you above 63.1% of the population. But an IQ score on its own does not predict academic, professional or personal success: it explains part of performance, not the whole of it, and leaves out motivation, habits, context and opportunity.
How much can an 105 vary if I retake the test?+
With the usual margin of error, your true score would sit between 94 and 116 with 95% confidence. Differences of a few points between attempts are normal and do not mean you improved or declined.
Does this count as a diagnosis?+
No. A clinical assessment is a couple of hours with a qualified psychologist under controlled conditions. An online test gives a useful estimate for self-knowledge, not a verdict. If you need a diagnosis for medical, educational or legal reasons, no internet test will do.
