Check to see if you have shortcuts installed. If not, grab it from the App Store here.
Here's the link to download the Virtual Schedule Shortcut. You'll need to know the order of your classes on a Day 1, so check your schedule if you need to!
Hold down on your home screen background to be able to edit it. Then tap the plus in the top left.
You'll need to scroll down to find it.
If it isn't defaulted to the Virtual Schedule shortcut, add it to your home screen anyway, and then edit the widget (by either tapping it or holding down on it).
If you're confused by this step, visit Apple's instructions on how to add and edit widgets.
This is all you need! If you have couple extra minutes and you'd like to customize the shortcut and take it further, head to the page linked in the button below!
