Kahoot

Kahoot! is a game-based learning platform, used as educational technology in schools and other educational institutions. Its learning games, "Kahoots", are multiple-choice quizzes that allow user generation and can be accessed via a web browser, phone, or the app itself. 
I suggest it teachers to use it while evaluating their students' knowledge about any subject instead of paper. Because it's very practical and students are eager to these kinds of things.

I and my friend prepared a short quiz about European countries. If you want, you can take the quiz by clicking here!
