Unformatted text preview: // \ Your TA‘s Name Your Name____;,'___2__._a=a———————— Anthropology 7: Human Evolution ' Winter 1996 \ ‘ Midterm Exam You must put your TA‘s name on the top of the first page and your name on the top of every page. We will deduct 3 points from your score if you don't do this. Please do this right now! There are 7 questions on the exam. You must answer all 7. These questions are meant to be answered in a few sentences. There should be enough space after each question for your answer, but if you run out of room, you may continue your answer on the back of the same page as the question (and nowhere else, please!). Each question is worth 11 or 12 points. The entire exam is worth 80 points, out of a total, for the entire course, of 200 points. Please use a pen to answer the questions. We will accept exams answered in pencil, but you will not be able to appeal the score given on any question answered in pencil. Good luck!

What students are saying

    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.
