About This Quiz

Think you are a general knowledge master? A lot of facts are considered basic knowledge, but that doesn't mean that everyone knows them as well as they should. While we all pick up certain things along the way, it is hard to tell who exactly knows what. In fact, many things which are considered basic common knowledge are actually incorrect, meaning that some people know a lot less than they think they do.

From science to health to politics and more, there is a lot of information that gets thrown at us on a daily basis. Facebook and other social media have made this even stronger. You could potentially be faced with a nonstop and unending flow of information about topics of all kinds if you wanted. While this provides learning opportunities, it can also make things muddy. After all, how much information can one person really retain? And where is all of it coming from? Knowing the source of a fact, account, or opinion can be even more important in many cases than knowing the fact itself.

If you think you are a general knowledge expert who has their facts straight, then put your brain to the test with this quiz!
