My IQ is only 100 (I took a professional IQ test for my psychology class a few years ago) but I am a smart person. I study and learn things all the time and have a good memory. I retain information really well, and people I know all say I'm smart. I've been studying quantum physics lately and astrophysics. It's really interesting stuff. But really hard to understand. I'm also taking a course on the big bang theory and dark matter, and also calculus (again). I don't think IQ really means much.
