Hi:
When you are inside the new form of the SAS Academy for Data Science, you either see a Virtual Lab Reservation System on the right side of your screen or you see an "Open Lab" button inside the class itself. Here are 3 examples of what you see in each level of the SAS Academy package:
If you click to Open Lab, then you should see the Virtual Lab Reservation System pane on the right side of the screen. If the Reservation System is locked, you will see the words "read the documentation" in blue. To unlock the reservation system so you can make your reservation, you need to click the link to open the documentation.
After you read the documentation, you'll be able to reserve a session to practice.
Hope this helps,
Cynthia
