About This Quiz

Do you think you have an all-around intelligence that will make a common sense quiz a breeze? Everyone likes to think that they are smarter than the average person, but there are so many kinds of intelligence that it can be hard to judge this. After all, some people remember every book they have ever read, but they might accidentally put their hand on a hot stove. Some people are masters at chess, while other people can fix or build almost anything. Some people write poetry which makes others cry, and others can do mental math like it's nothing. Some people don't test well but are excellent at talking to and handling people in social situations. There are so many ways to be smart, but for day-to-day life and business, some common sense is a must.   

Common sense is defined as a good sense in practical matters. Someone with good common sense makes the kinds of daily decisions that benefit them and others. It is an ability to read oneself, others and situations that is always useful. If you think you are a master of common sense, put your practical knowledge and horse sense to the test with this HowStuffWorks quiz!
