If you've already been using Studyo at your school, when a new school year arrives, you will automatically be connected to the new calendar and classes when the time comes.

IMPORTANT: You will get a message in Studyo telling you either that a new school year is being prepared or is available.

If the new configuration is being prepared, all you can do is wait until it is finished (a few days).

If the new configuration is available, you can select it by going to your profile menu (top right) under Other profiles.
