An IQ score of 120 sits in the sweet spot most people don't realise exists — it's solidly in the "Superior" range, but not so rare that it isolates you. Roughly 9% of adults score this high. Statistically, it's the level associated with the highest career success-to-effort ratio.
People at the 120 mark generally:
Research on income and life-satisfaction outcomes consistently finds that the strongest gains from IQ occur up to around 120. After that, additional points correlate with higher earnings only modestly, and may even slightly reduce social ease (very high IQ individuals report higher rates of intellectual loneliness).
An IQ around 120 is high enough to handle nearly any cognitively demanding career, yet common enough to find peers who think similarly. Many of the most successful entrepreneurs, managers, and creatives test in the 115–125 band.
Most people who test at 120 don't suspect they're that high — IQ at this level feels normal because you're surrounded by people of similar ability. A properly normed test is the only way to know. You can take a 25-question, time-calibrated estimate at quizvo.com in about 15 minutes.

About 9% score 120 or higher. Only ~6.7% land between 120 and 129 specifically.
For nearly any profession, yes. Above 120, raw IQ matters less than conscientiousness, emotional intelligence, and opportunity.
No. Mensa requires the top 2% — equivalent to an IQ of 130 on standard tests.
