Met 112: Final Exam Study Guide
Prof. Jin, Dec. 1, 2009
The final exam will be of a similar format as the midterm; closed book and notes,
multiple-selection section followed by short-answer questions. You will have 2 hours and
15 minutes for the exam.
To prepare for the final, I would suggest that you review your lecture notes very
carefully. Based on the results of the midterm, it should be clear that the more familiar
you are with your notes, the more effective you will be in answering questions within the
time limits. I would also encourage you to pay special attention to your homework
questions (Homework 3 and 4).
I would also suggest that you review the video we watched in class which is to enhance
clarity and understanding of the existing notes. In addition, review the conclusions of
your group project and what you ‘learned’ from this. Finally, a list of
questions/suggestions is provided below that should serve as a good review. However
note that this list is not intended to include everything covered in the course
or on the final exam, but it’s a good start.
