In reviewing the pre-course surveys for a public class scheduled in three weeks, an instructor discovers that some of the learners lack the prerequisite skills to grasp the new material. The BEST course of action for the instructor would be to:

A.
contact those learners and direct them to an appropriate class

B.
proceed with the course because the learners need to know the new material

C.
conduct a quick review at the beginning of the class that provides the learners with the necessary background

D.
cover the more basic material during this class and then schedule a second class
