IQ Tests?

Hi there!
I’m new here and I’m learning a lot of new things with all the information you are providing to me!
I’m interested to practice some techniques and training methods to improve my intelligence, but I think it would be a good idea to measure my IQ and them another one after some two, three months, take another one to see if it have been improved.

So, I would like to know if you have any reliable place to do these tests in NYC or Los Angeles, West Hollywood area and surroundings.

Thanks in advance for your help and attention.

Someone once told me that it might be possible to get free or cheap IQ tests through a university. Maybe contact a psychology department and see if there are any grad students who could do it.
