List of homework assignments: (Solutions provided after the submission deadline, by your TA's Michelle Bodnar and Daniel Kroes)

Lecture: Attending the lecture is a fundamental part of the course; you are responsible for material presented in the lecture whether or not it is discussed in the textbook. You should expect questions on the exams that will test your understanding of concepts discussed in the lecture.

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


Midterm Exams: There will be two in-class midterms: the first on Monday, April 24th (in class) and the second on Monday, May 22nd (in class). Note: Since there are no makeup exams, if you miss an exam for any reason then your course grade will be computed with the final exam counting 60% of your weighted average (see below).

Final exam: The final exam is scheduled for June 15th, 3:00pm-6:00pm.

You must pass the final examination in order to pass the course.

Grading: Your final score will be calculated as the maximum of the following two formulas:
(1) 20% Homework + 20% First Midterm + 20% Second Midterm + 40% Final Exam
(2) 20% Homework + 20% Best Midterm Exam + 60% Final exam

Note that you must earn a passing grade on the final examination in order to pass the course.

Regrades: Homework and midterm exams will be returned in the discussion sections. If you wish to have your homework or exam regraded, you must return it immediately to your TA. Regrade requests will not be considered once the homework or exam leaves the room. If you do not retrieve your homework or exam during discussion section, you must arrange to pick it up from your TA within one week after it was returned in order for any regrade request to be considered.

Academic Dishonesty:  Academic dishonesty is considered a serious offense at UCSD. Students caught cheating will face an administrative sanction which may include suspension or expulsion from the university. Click here for more information.
