Socrative is a web-based system that lets teachers and students set up quizzes and polling questions on any device that has access to the internet via a web browser. This includes iPads, smartphones, laptops, iPod Touches, etc. This makes it perfect for use in a BYOD classroom. For Android and IOS devices you can also access it via an app. And the best news is that it’s all free.
