Other resources:  
        OASIS has free tutoring, TuTh 2:00-3:50 Center 330, TuTh, 4:00-5:50, Center 356.
        The textbook web site has many online resources.

Section meetings:
        Tuesday section meetings begin January 14 (week two).  They review upcoming homework problems, collect the completed computer assignments, and (most weeks) give a quiz.  Please attend the Tuesday section in which you are officially enrolled.  If you want to change sections, please try to do so through the add/drop process.  In exceptional cases, you may attend another section.
        Thursday section meetings begin January 9, but the first computer assignment begins the next week.  They meet in the computer lab and you work on your computer assignment in section.  You are encouraged, but not required to attend the Thursday section in which you are enrolled.

Lecture topics.  A list of the topics covered in the lectures (usually updated a day or two after the lecture).

Homework assignments. Written homework assignments from the text book.
        We do not yet know if these can be graded; however, you must do them and hand them in.
        Homeworks are to be handed in weekly in the Wednesday lecture.  You can discuss them in the Tuesday section meetings.

Matlab assignments.  Weekly computer assignments, Thursday sessions, due Tuesday in section.
        Computer lab sections held Thursdays, in the CLICS NW MEZZ lab -- Upstairs in NW corner of CLICS in Galbraith Hall
        Common list of assignments for all Math 20F lectures.

        NEW: Check the course Matlab page for changes in due dates!

Quizzes.  Quizzes held most weeks on Tuesday, on preannounced topics, and take approximately 15 minutes.
        Quizzes will be held in the last 15 minutes of the Tuesday section meetings.  (This could change to be held during regular lecture.)
        The quiz topics will be announced in class at least two lectures in advance.  You may drop your lowest two quiz grades.

Midterm exams.  50 minute long exams -- during a regular lecture hour.
        Midterm #1: Wednesday, February 5. Now available:  Midterm #1 with answers: PDF format and postscript format.
            Topics: Through section 3.2.  (We skipped section 2.3 on Cramer's rule.)
            Review session: Tuesday evening at 8:00PM, Peterson Hall 104, February 4.
        Midterm #2: Wednesday, March 5. Now available:  Midterm #2 with answers: PDF format and postscript format.
            Topics: Cumulative, with 2/3 or more of the exam on material since the first midterm.
                        More information to be announced.
            You are not allowed to use notes, calculators, textbooks, etc.
            Review session: Tuesday evening (March 4th) at 8:00PM, Center Hall 115.

Final exam. Comprehensive exam covering all course material.  Now available: exam in PDF format and postscript format.
    Will cover material up through Chapter 6.2, page 347.
    You may use one sheet of notes (double sided, 8x11 inches).  No calculators or textbook or other material permitted.
    Exam Date & Time: Tuesday, March 18, 3:00-6:00 PM.
    Review session: Monday, March 17, 7:00-8:30PM, Peterson Hall 110.
    The "Basic Skills" study guide has been updated for the final. 

Grading.   The final exam and the two midterm exams will count the most, 35% for the final, and 20% for each of the two midterms.  The quizzes and lab assignments, and homeworks, and will each count for about 5 to 10% of the course grade.  (Percentages are only approximate and are subject to minor changes.)
    Although the percentages for homework assignments, quizzes and labs are low, they are a required part of the course.  If you completely omit doing the Matlab assignments, for instance, then your grade may be reduced beyond the indicated percentage.

Identification.   We have a large class, and it is time-consuming to keep track all the grades.  Please label all assignments and exams with (a) your name, (b) your student ID number,  and (c) the time of the section that you attend (so we can return it to you).  If you prefer to use a name different from that in the official UCSD records, please put both versions of your name!  Poorly labeled assignments may receive reduced credit.

Academic integrity.  Academic integrity is very important, and if cheating is detected (particularly on exams) it will treated seriously, possibly including referral to a dean. 
    For homework problems and computer lab work, it is permitted to work with other students or in groups or to get help from a TA or instructor, but you should write your solutions on your own.  If someone shows you an answer to a homework problem, you should wait at least 10 minutes and then try to write up the answer on your own.  This is to be sure you are really learning the homework material!  If someone helps you with a computer lab, you should be sure that you do all your own typing, and that you understand how to do it.
