Grading, Honor Code Policy, Processes and Procedures
Grading will be based on your performance on six four homeworks (weighted 25% 30% in all), one class project to be done in pairs (weighted 25%30%), and two exams (weighted 25% 20% each). Each project team will be expected to give an in-class presentation on their project at the end of the semester, and to submit a report by December 11, 2015.
The purpose of the homeworks is to train you to solve problems and to help deepen your understanding of concepts introduced in class. Homeworks are due on the dates and times specified in the course schedule. Homework is worth full credit when turned in on time. A 10% penalty per day will be levied on late homeworks, up to a maximum of 6 days. No submissions will be accepted more than 6 days after the due date. If you believe we have made an error in grading your homework or exam, please bring the matter to our attention within one week after you receive the graded material.
You will be expected to follow the Honor Code in all homeworks and exams. All submitted homeworks are expected to be the result of your individual effort. You are free to discuss course material and approaches to homework problems with your other classmates, the teaching assistants and the professor, but you should never misrepresent someone elseâs else's work as your own. If you use any material from external sources, you must provide proper attribution (as shown here). Exams 1 and 2 are pledged under the Honor Code. They test your individual understanding and knowledge of the material. Collaboration on exams is strictly forbidden. Finally, it is also your responsibility to protect your homeworks and exams from unauthorized access.
If you believe we have made an error in grading your homework or exam, please bring the matter to our attention within one week.
Accommodations for Students with Special Needs
