Baaahhhh......IQ tests are garbage (especially online tests). I tested very high in elementary school; however, I have taken 3-4 online tests in recent years & almost always maxed them out (usually timed word-association tests). I have always known that I was pretty "smart," but the only way that my "intelligence" has played a real important role is by helping me identify the things that have REALLY helped me to be successful:
1. Common Sense
2. Ambition
Quite frankly, no one gives a rat's @ss how "smart" you are...and you will NEVER EVER be asked your IQ in a real-world situation. If you have "street smarts" & a little "drive," the average person can EASILY surpass your average brainiac. I have a friend who is so outrageously "intelligent" that he is the only person who has ever made me feel intellectually inferior. However, although he is a friend of mine, I must say that this guy is an absolute nut (like mass-murder, stalker, OC-Bomber, etc, etc) He has a genuine photographic memory & puzzle-solving skills like you would-not-believe. On the other hand, he has NO idea how to act around people, & often times really creeps out people that he doesnt know...and he has no idea why. No "normal" social skills, even though he spends a lot of time around people, just like anyone else.
Anyway for what ever it's worth....yeah 147 is quite high for a REAL test (not an internet test - IMO)
Median = 100
Standard Deviation = 15
+/- 1 SD (IQ of 85-115) = about 68% of population falls within this range.
+/- 2 SD (IQ of 70-130) = about 95% of population falls within this range
+/- 3 SD (IQ of 55-145) = about 99.9% of population falls within this range.
