Mensa has set a percentile as cutoff to avoid this confusion.Candidates for membership in Mensa must achieve a score at or above the 98th percentile on a standard test of intelligence (a score that is greater than or equal to that achieved by 98 percent of the general population taking the test).The result on one test of 132 can be the same as a score 148 on another test.Some intelligence tests don't use IQ scores at all.

You can take something close to a real IQ test by taking a local Mensa test. Also, if you've ever joined the US Army :-) then they take tests that correlate (e.g. Most general intelligence tests have high correlations (that's how "g" was discovered in the first place).
So if you're a high schooler, you can just look at your SAT Math score, it can probably be reasonably translated to IQ.
The online "pay with credit cards" aren't proper IQ tests, they are only marginally better than the free ones, so don't bother to pay.
If you want a fake number that has the "IQ" label on it, then just search for "free IQ test".
