If you are a teacher using Google Classroom with your students, I would highly recommend that you suggest to them to bookmark your Google Classroom in the browser.
After they join your Google Classroom, have them click on the star on the omnibar in Google Chrome, and allow them to bookmark the page to the bookmark bar.
This will allow them to arrive quicker and more direct to your Google Classroom. Students can have multiple bookmarks on the bookmark bar for all of their classes.
