Yes, you can! During your free trial of Educake, you can do anything that subscribers can do. Just like we do for subscribers, we'll add your students for you so you can set some tests to them and see how Educake works for your school. You'll also have access to all the same content you'd have if you subscribe.
If you choose to subscribe to Educake, everything from your trial will carry over - that includes students you've added, teachers who have created accounts, and tests that have been set.
