ACHS provides all students with a free license to the online-only version of Microsoft Office. You can access at office365.com and use the same credentials you use for all your ACHS services (Canvas, Google, Portal).
If you download the Microsoft Office desktop apps to your computer, you will have to use a different email address to access those and/or purchase a license. Most students find the online version to be more than sufficient. Plus, it has the benefit of saving your work in the cloud, so you don't have to worry about losing your files in a computer crash, and you can easily access your work on any computer or mobile device.
Also, note that all ACHS students have access to Google Workspace. And Google Docs can be saved or exported as Word Docs or PDFs.
Assignments at ACHS can be submitted as Google Docs, PDFs, or Word Docs.
