Ahem. I'm from America. I'm finishing up calculus after half a year of study at 14 years old. I have an IQ of 138/139 (I don't remember which)... which is funny, because my memory is in the 99th percentile(which means it's better than 99 percent of the rest of the world). Happy?

Add more questions, 20 is far too easy. Put 50 in or something, a lot of people would struggle to reach it but at least you can improve your score that way, getting to 20 isn't a challenge.

I think a few more problems could be added or a little time taken off. I know it's random and not everyone is going to have multiple problems that had a 1 digit number in them like I did, but the average score is 16/20 so a lot of people are finishing this easily.
