My name is Ivan Ivec and I come from Croatia.
I'm a teacher of mathematics with a PhD degree in mathematics.
I'll present here my IQ tests and other activities. See home page.

We don't fully understand what constitutes intelligence,
especially when measuring away from the mean.
Take my IQ tests only for fun and as an intellectual challenge.
