Yes you can! As a tutor, you’re able to enter a lesson before the start time to prepare, so if you’d like to upload a few documents beforehand, or have something ready on the whiteboard, you can do so!
To join a lesson early, you’ll just need to click on the join lesson button either using the upcoming lessons section on your dashboard, or by going to your lessons and using the join lesson button next to the lesson in question. This will take you through to your classroom for the lesson!
Your students won’t be able to join until the exact lesson start time, so you don’t have to worry about them joining suddenly before the lesson - you can prepare the lesson before and have it ready for the student to start straight away! If a student clicks the join lesson button slightly early, they'll be kept in a waiting room until the exact lesson start time, at which point they'll then be automatically taken through to the session!
