As a faculty member, I feel it is my responsibility to be sure those students understand the requirements of the course and that they have the skill set to be successful in the course. It can be very frustrating and discouraging for students to feel as if they are in over their head right from the start of the course, so the first week I do a review of content that I know is an expected foundation to be successful in the course. If the students are not adequately prepared for the course, I can pick it up right away and intervene with some tutoring before they get buried in the new content.
