Maybe it just means that your not great at taking the type of tests that you've been given. There's a lot of controversy around IQ tests and what they actually measure, as there is some cultural bias inherent to them. And at the end of the day does it really matter? Unless of course you're bound and determined to get into Mensa...

I've never been asked about IQ in school, undergrad or grad, or in a job interview.

If you're reading and understanding philosophy that puts you ahead of a lot of people, but remember people manifest there intelligence in different ways - some are brilliant at maths, but rubbish at languages and vice versa, some people are incredibly artistically gifted.

I think it's more important to find where your talent's interests lie and explore them, than worrying about what any test says.
