Course web site :   Homework assignments, class notes, supplements, and solutions will all be posted
at the course web site, .

E-mail:    I encourage students to make use of e-mail for quick correspondence with me regarding lecture material,
homework problems, or whatever. I will also use e-mail to communicate with the class at large. I can often be reached
at night or on weekends by email. Students are responsible for making sure I have their correct email address
and checking their email daily. Important messages will sometimes be sent to the class by email.

Homework Policies:  

Exams:  Two mid-terms and a final exam (Thursday, Dec 17, 1:30pm-3:30pm).  The final will just be a third "mid-term".
If you know ahead of time that you will miss an exam you must notify me before the exam. For emergencies, I will
accomodate those with valid, doumented excuses and who have given me timely notification.

Grading: The course grade will be based on the homework and  exams. The lowest two homework scores will be dropped.
The exam grades will be uniformly "shifted upwards" if I deem necessary. The relative weights will  be adjusted at the end
of the semester to maximize the total for each student, with the homework in the range 15-25% and each of the mid-terms in the
range 15-35%. In practice, this means that your weights are either 25% for hw and 15,25,35% for your exams, or
15% for hw and 15,35,35% for exams, whichever assignment of weights maximizes your total score. The letter  grades
corresponding to numerical scores will be determined after reviewing the class performance as a whole.

Tips for doing well :

Academic honesty:  The University of Maryland, College Park has a nationally recognized  Code of Academic Integrity,
administered by the Student Honor Council. This Code sets standards for academic integrity at Maryland for all undergraduate
and graduate students.  As a student you are responsible for upholding these standards for this course.  It is very important
for you to be aware of the consequences of cheating, fabrication, facilitation, and plagiarism. For more information on the
Code of  Academic Integrity or the Student Honor Council, please visit

The University has adopted an Honor Pledge, which is a statement undergraduate and graduate students are asked to write
by hand and sign on examinations, papers, or other academic assignments not specifically exempted by the instructor.
The Pledge reads: "I pledge on my honor that I have not given or received any unauthorized assistance on this
assignment/examination." In this course it is assumed that all students have entered the University agreeing to the
honor principle which would apply in general to all campus activities, so usually no specific statement is required.
