Problem Sets, Pre-Midterm: #1 Sept. 30, 2010 due Oct 7, 2010 #2 Oct 7, 2010 due Oct 14, 2010 #3 Oct 14, 2010 due Oct 21, 2010 #4 Oct 21, 2010 due Oct.28, 2010 Problem Set, Post-Midterm #5 Oct. 28, 2010 due Nov. 4, 2010 Exercises: as assigned on the Lab Notes Organization ( Cont.) Takehome Project: An exercise to test your quantitative and writing skills. You can work collectively but the 2-3 page report must be yours. Last Fall we also did group projects with PowerPoint presentations and I will probably repeat this format. Your grade for the course will be based on your scores on the midterm(18%), final(37%) and 2 projects(each 18%), and your effort as indicated by problem sets and lab exercises turned in for credit(9%). Of course the latter are more important than the weight indicated. I distribute the grades by letter, weighing the problem sets one third of a grade point, and by total score for the class, and reconcile the course grades.

### 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.

Dana University of Pennsylvania ‘17, Course Hero Intern

• 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.
