A. Linked courses are a set of courses that are assigned to a specific group of students (e.g., Period 1 CC Math 7A and Period 2 CC Math 7 Tutor Lab A) and are the equivalent of double-blocked classes. In order to link courses, the same group of students must be enrolled in both classes.  Combined courses are the equivalent of double rostering, where a teacher is assigned various groups of students to provide instruction for two or more courses during the same period (e.g., English 9A and English 9A – Sheltered).
