This is best for individual review time. It is NOT like Kahoot in that students work at their own pace. You can project the leaderboard on the screen- but I didn’t like how it showed a red bar that grew as students got more answers wrong!
Students do have to join the quiz using a code (or it can be embedded into Classroom- which only sometimes worked for us), but once they have the code, they are good to do the quiz whenever.
I did like the ease of the creating the questions and answers (faster than Kahoot), and the options to add memes. 🙂
