Don't bet on it. Many lectures will complement the textbook. It is important, therefore, that you attend class and take good notes. Poor attendance usually results in a poor final grade.
Exams consist of multiple choice questions.
The exams will emphasize vocabulary and concepts. Therefore, pay particular attention to words or terms in the textbook that are italicized or appear in bold print. Do the same for words or terms that are emphasized during lectures. Pay close attention to graphs, charts and pictures. Make up exams are not given unless arrangements are made with me before the exam is given to the class.
