The information for some units is presented almost entirely in the Study Guide; in other units, the Study Guide refers you to assigned textbook and Reading File readings. Each unit begins with a set of objectives. When you have studied the material in the unit, answer the study questions at the end of the unit and check your answers with the key, and then review the objectives to satisfy yourself that you can meet them. If necessary, review the material before continuing.

If, after completing a unit, you feel that you do not fully understand the course material, or if you are experiencing difficulty with the study questions, please contact your tutor. It does not matter how much additional assistance you require—we are committed to helping you master the course objectives, and will do everything we reasonably can to help you do so.
