This a collection of questions gleaned from a variety of sources (created by your TAs, me, past instructors, the web etc.) on material from our fourth ¼ of the semester. I am hoping that this might help you review material from this final section of the semester. These questions are not meant to be your exclusive, “one and only”, study guide to the course. Do not treat them as such! Please note that, in particular, these questions only cover the fourth and final quarter of the semester. They do not represent a cumulative review of the entire semester. The final exam, on the other hand, will be 50% cumulative from the entire semester (the other 50% is based on the fourth quarter alone). To review for that you may look at past practice question sets from earlier this semester in combination with the material presented here. In particular please note that: 1) I generally try not to re-use questions throughout the semester. Do not expect these exact questions to be reproduced on an exam even if the same topic is covered. 2) This is a sampling of the material we have covered in lecture, discussion and in the book. Some material here may not actually appear on the exam. Similarly material on the exam may not appear here. When in doubt about something, whenever confused, please come to office hours, talk to your TA or make an appointment with me! 1.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
