Instructor's comment: It appears that many people in the class are doing well. The number of people in the A/B range is greater than the number of people in the C/D/F range.

To those who are doing well: keep up the good work.

To those who are struggling: take measures to improve your performance. You should come to class with regularity. Try to do the homework and not just hope you can come into class and complete it by writing down what we go over. You're not likely truly learning anything. You're just getting points (in an academically dishonest manner, I might add). The truth is revealed by your performance on the test. Moreover, this is NOT a class where you study by reviewing your notes for an hour or so before the test. You should spend several hours studying. Yes, several hours. This includes working through the sample multiple choice problems. This includes going over your past homeworks. This includes reading the text. You just can't slack your way through economics and expect an A or B. For most of us those grades are earned by having an interest in the material and spending time learning the material.

If you think you are spending a lot of time studying but your performance is not as expected, you should discuss this with the instructor. You will be advised on measures you can take to improve your study skills.

Good luck with the remainder of the course.
