Microsoft 365 is the Flatest version of Office and includes popular apps like Word, Powerpoint and Outlook.
If you are a student or teacher with an active school email address, you can get Microsoft 365 for free.
Those looking to use Office on smartphone can download standalone apps like Word and PowerPoint or go with the Microsoft 365 app.
In case you don't have a student email and are on the PC, you can use Microsoft 365 on the web which lets you access PowerPoint, Excel and Word for free.
The only downside of using the student version is that you will lose access to Microsoft 365 when you finish school.
