Usually when students sign up and pay for their course, they are automatically accepted into all the classes with in that course.
However sometimes the school will only accept you into part of the classes in the course. Then later in the semester they will ask you to enroll into the future classes.
To enroll in a class, do the following:
1. Located in the upper right, click on "My Dashboard"
2. Now select the "Enroll" tile
3. Make sure the Toggle at the top is set to enroll in class, select the checkboxes next to your class, and click Sign Up
Then the school will have to accept your "Class Enrollment" request and then you will be in.
**Note Really Important**
This Enroll in a Class option only appears, if the student has already signed up and paid for their "Course". Courses are the entire program, and classes are sections of that course.
If you haven't enrolled in a course, reference this article below:
