I recently found this site, that probably most of the world has already heard of one time or another. However, I have seen that there are several useful ways to use the quiz features.

It is very easy to make quizzes to test yourself, whether it is studying for tests or just reinforcing knowledge. Enter the questions in one column, and the answers in another. When you play, the system will show the answers you get right as you type them in.

While a lot of the games are either frivolous or completely useless trivia (which is actually the point of the site to begin with), there are a couple of science games, such as the periodic table, triangular numbers, and electromagnetic spectrum that have educational value. The good thing is that the site becomes rather addicting, so you will be gaining knowledge without pain!

Elementary school teachers can also make quick arithmetic drills for their students on this site because they can utilize the time limit wisely; I remember doing a lot of "mad minutes" when I was young, which involve solving a certain number of addition or subtraction problems within a minute. In fact, there is already a version of it on the site.
