You're not in this alone! For any questions about errors with the grader, running of cells in the Virtual Machine, or with the Lab content, we suggest you contact the Teaching Assistants either in the forums or via a session of live office hours hosted on Zoom each week. All office hours are displayed on your calendar in your local time zone.
You may choose to attend any session regardless of the project number you are working on. Each Teaching Assistant is well versed in the content and they will be able to assist you with content related questions.
If you want to exchange ideas and experiences with your peers from across the globe, we highly encourage you to take advantage of the forum, which you can access via the Project overview section inside the learning platform.
