How do I access Office365 for free?
You can use word online for free by clicking the following link - Login | Microsoft 365 (office.com)
You will have to create or login to your Microsoft account but it's free to use through a web-browser.
Alternatively, you can have a look through the orientation module on Moodle and on the side underneath 'Requires Systems' it has a 'Word & PowerPoint' tab outlining another way you can access them both for free.
