You may wish to attend the lectures for the course to help you orientate your class teaching and synchronise your approach with that of the lecturer. Some courses require GTAs to attend lectures. Lecture materials may be available on the course web site or virtual learning environment. Looking at past exam papers can also help you determine the themes and issues that should take a greater priority in your teaching. Some class teachers describe allocating the content of their classes into two planning columns, 'must have' and 'nice to have'.
