You can join a lecture after logging in and by selecting one of the lectures presented in the active sessions tab.
There is a lecture planned in the future which you will be able to join. All planned lectures with an actual starting time larger than 15min from the actual time, will be visible in the ACTIVE Session tab. Therefore, there is not a possibility to join a lecture planned too far in advance.
When a lecture has not been started by the lecturer and the lecture is within 15min before the start, a student will be able to enter the ' Classroom', by selecting the planned lecture. A video or wallpaper will be circulating until the lecture has been started. That is the only available section for the student before the start.
