Socrative

 

In socrative, You can create quizzes and make them multiple choice, true-false or short answered questions. You can also look up to answers and see how many students answered your questions.

 This is a very simple website and easy to understand what you should do, This website is created for teachers and students, You can join there as a teacher and create questions for your students or you can join the students part and answer the questions.

There is an example from my test at the top of the page.
