Grading and Course Policies
Math 20D Spring 2008 Introduction to Differential Equations

Reading:
Reading the sections of the textbook corresponding to the assigned homework exercises is considered part of the homework assignment and it will be expected that you read the assigned material in advance of each lecture. Furthermore, you are responsible for material in the assigned reading whether it is discussed in the lecture or not.

Discussion/Matlab Sessions:
 
The discussion sections are an integral component of the course, and as such you are required to attend.  As all six of the discussion sections are full, only attend the discussion/lab sections in which you are registered.  In addition to discussion sections, you have a reserved time in the computer lab on Thursdays at the same time as your Tuesday discussion section.  The lab sections are scheduled so that you may get help with Matlab from your TA. You are expected to make use of the lab sections; questions specific to the operation of MATLAB will likely not be answered outside of the lab sections. These lab sections complement the lecture portion of the course, and have homework problems of their own.  These homeworks are due the following Thursday in the lab section.

Lecture Homework:
 
Homework will be assigned on the course homework page and should be completed by the discussion section on the indicated due date. Homework will not be collected; rather, your homework will be measured by your performance on quizzes. Completing the assigned homework is vital to your understanding of the subject material. You should make every effort to complete the homework assignments and seek help with problems you have not been able to solve.

Matlab Homework: 
Matlab assignments will be assigned weekly and should be turned in to your TA during the Thursday lab section on the due date indicated on the homework page. There will be a single drop box available for all Matlab Sections in APM 6th floor.
Labs can be handed in either in the lab section or in the drop box. If you use the drop box, then labs must be in the drop box by 8:00pm on the due date.
No late assignments will be accepted. Your cumulative MATLAB grade will be based on the best  7  of the  8  MATLAB assignments and on your performance in the Matlab exam (see the Matlab homepage for further information). You may discuss the Matlab assignments with your instructor, TAs, and other students in the class; however, the assignment you turn in must be your own: A plagiarized assignment will be considered evidence of academic dishonesty.

Quizzes:
 
There will be five quizzes given during the lecture on certain Fridays; please see the homework page for the dates of the quizzes.  Each quiz will consist of two or three problems, similar to the assigned lecture homeworks. You will be allowed to take the quiz home, complete it, and turn it in on the following Monday in the Lecture.  There will be no makeup quizzes, and late turn in will not be accepted. The quiz assignment you turn in must be your own: A plagiarized assignment will be considered evidence of academic dishonesty.

Exams:
 
There will be two exams,  fifty-minutes each.  See the homework page page for the dates of the exams.  You will be allowed fifty (50) minutes to complete each exam.  Each exam will have four or five problems. You may bring with you to the exams one 8.5 by 11 inch handwritten sheet of notes, which can be written on both sides; no other notes (or books) or calculators will be allowed.  There will be no early or makeup exams.

Final Exam:  Friday, June 13,   7:00-10:00pm. Place: Solis 107 (lecture room).
You may bring one 8.5 by 11 inch handwritten sheet of notes with you to the final examination; no other notes (or books) or calculators will be allowed. 

Bring your personal photo ID to the exam.

It is your responsibility to ensure that you do not have a schedule conflict involving the final examination; you should not enroll in this class if you cannot take the final examination at its scheduled time.

Grading:
Your course grade will be based on the maximum of the following two decompositions:
    • 15% Quizzes (best 4 of 5)
    • 15% MATLAB Lab Assignments (best 7 of 8)
    • 20% Exam 1
    • 20% Exam 2
    • 30% Final Exam
    • 15% Quizzes (best 4 of 5)
    • 15% MATLAB Lab Assignments (best 7 of 8)
    • 20% The best of the two Exams
    • 50% Final Exam
In addition,  you must pass the final examination in order to pass the course.  Note:  Since there are no makeup exams, if you miss an exam for any reason, your course grade will be based on the weighted average that counts the final examination 50%.

Final grades will be assigned based on the following scale.  We may curve the scale to be more lenient, depending on the final grade distribution, though this is at the sole discretion of the professor. 
A+ A A- B+ B B- C+ C C- D F
100-97 96-93 93-90 90-87 86-83 82-80 79-77 76-73 72-70 69-60 Below 60


Academic Dishonesty: 
Academic dishonesty is considered a serious offense at UCSD. Students caught cheating may face failure in the course and an administrative sanction which may include suspension or expulsion from the university.
