You must also participate as a subject in 5 hours of psychology experiments in the department. These are ungraded but must be performed to pass the class. If you do not want to participate in psychology experiments, you will need to do an additional written assignment. See me for details. The idea with the exams is to give everyone a chance to show their strengths.
Some people write good essays, others are good at multiple choice questions.
Thus the exams contain questions of both type. You'll have two one-hour midterms and a two hour final. The final is cumulative, but will be weighted towards material covered in the last third of the course. People tend to grump that my exams are too long and too hard. They are designed that way.
