rags to riches helps you because it  is educational and it is fun because you want to keep helping the people that need grains of rice. i have never used quia and all i really know about it is that it is what you use when you take tests. i think it helps because when you use computers to take tests it saves the trees by using technology instead of wasting so many trees!!! well it also helps by when you take tests on the computer it can save them instead of maybe losing the test and never finding it again.
