How do you find out your IQ?

Answer 1

"you can search the internet♥

You search it up on Google. There are many different ways. But bewarned, some are viruses and scams and NEVER type in your mobile because you repetedly get text messages, phone calls, chain e-mails and many more pestful problems. I, myself have done this before and fell for it, now my phone is broken so I have had to purchase a breand new mobile phone. Only ever do the test if it will SHOW you the result afterwards on the web page once it is complete.

Actually, you have no hope in hell of obtaining a genuine IQ test on the internet. Genuine IQ tests are legally only administered by trained, qualified psychologists. Anything else is fake and usually has a built in bias to make you think your IQ is much higher than it really is. They use this as a lure to get you to give them your email address or worse, money for a complete analysis that is completely made up.
Ask your school or doctor to test you I got mine at school it was 138 and I am 11
The easiest way is to try several online IQ tests.

Ideally, you would see a professional.

You could also check with Mensa -- they have exam sessions, during which you can take a certified IQ test (and even join them, provided you're in the top 2% of the population).
