Firstly, check if you can reset your deadline. You can click "Switch Schedule" on your computer or "Reset My Deadlines" on Coursera app. This will ensure that the content is up-to-date without losing your progress.

Secondly, open the exercise you would like to work on. If you still run into issues when opening the tool, choose one of the following documents instead so that you can work on the exercises:

• Google doc (you will be asked to make a copy)

• PDF attachment

• docx attachment
