You can now prepare your lessons as soon as they are confirmed and shown as 'Upcoming'.
To prepare the classroom, simply visit your Bookings Page and use the 'Prepare' button (as shown below) to launch the classroom and upload any materials/notes you'd like to add in advance.
The classroom is saved automatically, so you can either close the tab and return to Sherpa when it's time to launch your lesson, or if it's close to the start time, stay in the classroom until your student joins and have the lesson as normal.
