If you are a student, you can select a new topic to begin from your Dashboard. Use the right arrow to scroll through all the available topics:
Please note that you can only complete one topic at a time. If you have already started a topic, you will need to complete it or cancel it before you can begin a new one. Completing a topic includes earning the required number of XP in the relative Dialogue Space (usually 50 XP). You will also need to complete the topic’s Progress Tracker before you can begin a new topic.
