Hi Laura,
Update:
To better support customers facing the new reality of work remotely or attending classes remotely, Autodesk has introduced a temporary Extended Access Program for several of our flagship cloud collaboration products, including BIM 360 Docs, BIM 360 Design, Fusion 360, Fusion Team, AutoCAD Web and Mobile, and Shotgun. This program allows for free commercial use of the participating products until May 31, 2020.
Typically, the commands and tools in the AutoCAD web app are only available to AutoCAD and AutoCAD LT subscribers and are not available to students. During this Extended Access Program, all commands and tools in the AutoCAD web app are available for everyone.
Here are some additional resources to help you get started:

Best regards,
Jon
