Hello there, @100383804443653 ...
Please review this Guide: Why can't I access my Course as a student? - Instructure Community
You'll also want to check out your "Courses" >> "All Courses" screen to see if you can see any or all of your courses there. If you are not finding your courses listed on that screen, you will need to speak with someone at your school to figure out why those courses aren't yet showing up for you. You can try contacting your school's local Canvas administrator or someone from your school's Online Learning/eLearning department. They should be able to help you further with this.
