How do I enroll in a class?
If your instructor didn't enroll you in the CritViz course (manually or in bulk) they probably are using an open enrollment code. If the instructor set the course to use "Open Enrollment", the instructor will have a unique code that anyone can use to enroll in the course. They can email this code to the entire class, or put the code on their syllabus etc. If you have this code, and you have a working CritViz login, you can enroll yourself in the course by navigating to the "Students: Join a Class" button. This is found under your username located in the black bar at the top of every page.
When you click on "Students: Join a class", you are presented with a form field where you enter the specific enrollment code associated with that class. Enter the code, and hit "Join" and you are in. You should now see that course in your course list page (found by clicking on the CritViz logo button in the black bar at the top of every page).
