  In order to manage a course group in a course
  As a user

      | teacher1 | Teacher   | 1        | [email protected] |
      | student0 | Student   | 0        | [email protected] |
      | student1 | Student   | 1        | [email protected] |
      | student2 | Student   | 2        | [email protected] |
      | student3 | Student   | 3        | [email protected] |
