There is a question that we receive once in awhile: Is this website free or do I have to pay to access the quizzes?
The answer is simple: Quiz-Tree is free. It is supported by our advertisers so that everyone can enjoy free educational activities. You have an option of creating a user account to help you track your progress, but that is also 100% free.
So, what are you waiting for? Visit Quiz-Tree and see how learning can be fun!
