get smart and very hard
There are smart people, there are others who think they are smart but aren't really and there are others who just keep trying. It doesn't matter who you are but it is important that you try. With practice you will improve and become smarter.
This quiz is has a variety of questions, some factual and others not so. I enjoyed putting it together based on things I learned in school and from friends. After you've taken the quiz why not ask your friends the questions to see how they go!
