If you missed a student when creating your class, you have different options:
1. You can give the students the class code that you'll find when you click on "classes" on the left. Students can create their own user account via this link. After the student account is created, students can enter the class code in the app and will be assigned to the class. They will appear in the student list now.
2. You can create the account again. Go to "Students" on the left and chose "Add students" on the right. We suggest you to create the account by adding your student with his/her full name by first clicking on "create accounts" and then on "type student names individually". Click then on "import" and create accounts". You can download the list "Instructions to join" afterwards.
