IQ 106
Is 106 a good IQ? What it means
106 sits in the middle of the Average band. Here is where that puts you on the curve, how common it is, and what the score does and does not predict.
Short answer
An IQ of 106 is a little above average. It is higher than about 65.5% of people, which puts it at the 65.5 percentile. About 1 in 3 people score 106 or higher, and the WAIS-IV labels it Average (90 to 109). It is 0.4 standard deviations above the mean of 100.

What an IQ of 106 means on the scale
Modern IQ tests report a deviation IQ: scores are standardized so the mean is 100 and the standard deviation is 15 within each age group (Wikipedia: Intelligence quotient). On that scale 106 is 0.4 standard deviations above the mean. It sits inside the 85 to 115 range, where about 68% of people score. (the 68-95-99.7 rule)
In a room of 30 people your age, about 10 would be expected to score 106 or higher. Put another way, about 66 out of every 100 people score below 106.
The Average band: 90 to 109
Average covers 90 to 109 on the WAIS-IV scale (Wikipedia: IQ classification) and is the largest band by far: about 49% of people score in it. Half of everyone tested lands within this 20-point stretch.
The band is centered on 100, the mean of the scale by construction (Wikipedia: Intelligence quotient). 106 is on the upper side of the middle: 6 points above the mean, and 4 below the High Average line at 110. Within this band, differences of a few points are smaller than the error of any test, so 95 and 105 are best read as the same kind of result.
Where 106 sits inside the band
106 is 16 points above the floor of the Average band (90) and 3 points below its ceiling (109). Of the people who score in this band, about 81% score below 106.
Clinical IQ scores carry measurement error of around plus or minus 5 points at 95% (Wechsler, 2008). A measured 106 is consistent with a true score anywhere from 101 to 111, which is the 52.7 to 76.8 percentile. That range spans two labels, Average and High Average, so the band name is the least certain part of the result. A short online test has a wider range than a clinical one, so read any single number as the middle of a span.
What an IQ of 106 does and does not predict
An average score means your reasoning on these puzzles matched the typical person your age. It leaves plenty of room for strengths the test does not measure, from knowledge and skills to persistence.
Across large groups, the links are real. General intelligence at age 11 correlated 0.81 with exam results at 16 in about 70,000 English children (Deary, Strand, Smith & Fernandes, 2007), a review of 85 years of workplace research put the link with job performance at 0.51 (Schmidt & Hunter, 1998), and a 2007 meta-analysis found correlations of about 0.56 with education and 0.23 with income (Strenze, 2007). Those describe tendencies across many people. None of them let anyone predict an individual life from one number. The guide to what IQ predicts explains what a correlation of that size means.
Same score, different tests
Older Stanford-Binet forms used a standard deviation of 16, and the Cattell Culture Fair III scale uses 24 (Wikipedia: IQ classification). The same percentile as 106 on a standard-deviation-15 test reads as about 106 on the first and 110 on the second, so check which scale a number is on before comparing scores from different tests.
