text: how is an i.q. ranked; what is good, bad, etc.?   i work at a child psychologist office and i grade intelligence tests all the time. if you want to determine your iq, go see a psychologist because online iq tests can be inaccurate.  100 is average and most people are around 100 iq.  140 and over - genius or near genius - 2.2% (of the population) 120-140 - very superior intelligence - 6.7% 110-120 - superior intelligence - 16.1% 90-110 - normal or average intelligence - 50 % 80-90 - dullness - 16.1% 70-80 - borderline deficiency - 6.7% below 70 - definite feeble-mindedness 2.2%  fyi, i'm about 124.  if you have a very high iq, you may be eligible for a membership with mensa.  but i wouldn't worry over iq scores. they really just helpful to determine needs (gifted, special education, etc).
