Hi Jessica Steel,
Thank you for reaching out to Microsoft Q & A forum.
There are two ways to access the sandbox for your module. You can either use the sandbox from the previous module if it is still open in another tab, or you can use the sandbox available in Unit 5 of the current module. To ensure smooth use of the sandbox without confusion, consider the following steps:
1.Open the training module in two different tabs—one for the sandbox page and another for navigating through all the units of the module. This way, you can keep the sandbox open on page 5 in one tab while continuing your learning in the other.
2.Use a split-window setup by opening the sandbox on page 5 in one browser window and resizing your windows so that each occupies half of the screen. This allows you to view the sandbox in one window while progressing through the module in the other.
3.Use another device, such as a tablet, mobile phone, or another computer, to open the sandbox while continuing the training module on your primary device.
