Rounds were build to simulate the rounds from standard Extemporaneous Speech events, to allow you to practise as if you were competing. You can access it by clicking on the clock icon from the navigation bar.
Then, just type in your topic question and set the duration for the round (the timer is set by default to 30 min., as that is the standard length, but you can set if to anything you want between 1 and 60 min.). You can now start Extemp Rounds using Practice Questions as well. Click Start Round to add your articles.
When the round starts visit your Folders, do a Smart Search or open the News Feed to add articles to the current round, by clicking the ‘+’ icon next to their title. After you've added the articles, you’ll find them in the Round, to quickly switch between them and highlight the information you need (highlighting is not available for News Feed articles which have not been saved to Prepd).
