I would like to open a discussion about the working materials in the Jupyter Notebook labs. About the quality, the positive or negative remarks. Also, about some parts that are a bit unexplained or can be done differently. In other words, my idea is to post some feedbacks about the Jupyter Notebook labs.1 vote

Give students the code in .ipynb files to store locally rather than hosting them in a faulty cloud service
- This service is being paid for
- Your Jupyter Notebooks service is often down
- The course is paid for on a monthly basis (Time = Money)
You should provide the .ipynb files for student to store on their own device to complete lab sessions
Respond to user queries/ Get it fixed quick
Refund everyone for the time the service is down/intermittent.
Provide the service at no cost.8 votes
