Your grades should be available by May 9. Please click on ASU Interactive to access your grades then.

The most important problems for the final exam are the problems on the three midterm exams. For section 6.2, the examples shown in class and homework problems assigned are important. After you make sure that you understand how to solve all problems on Exams 1, 2, 3 and problems of 6.2 mentioned above, you next review and practice quiz problems, next homework and webwork assignments.

Some more properties of eigenvalues and eigenspaces which will help to determine whether a matrix is diagonalizable will be presented in class on Apr. 19/20. Next Exams 3, 2, 1 will be explained as a review for final exam.

HW 7, HW8, HW9, Quizzes 6, 7, 8 solutions are available on the bulletin board (next to PSA 827) outside my office PSA 836.

My computer at home is sent to be fixed. If you have questions, please come to my office hours. No e-mail reply will be sent out after 5pm or over weekends starting March 30.

**Bonus Exam Point Program**:
(After you receive bonus exam points,
your Exam 2 can be many more than 100
points.)

1. If you get perfect score with **all
the justification** of the answers to
the quiz questions ( starting at Quiz 6),
then you receive
**two bonus exam points** added to
your Exam 2.

2. If you turn in ** stapled
**homework (starting at HW 6)
with perfect
score and all the detail work
on time,
then you receive ** one bonus exam
point** added to
your Exam 2. (Note that if you only
wrote down your answer without
showing your work, you do **NOT**
receive any bonus exam point even if
all your answers are correct.)

3. If you finish the
WebWorK assignment (starting at WeBWorK
Chapter-5-part-2) 100% correct by the
bonus deadline, and **turn in** a
copy of a print-out ** in class**,
then you receive ** one bonus exam
point** added to your Exam 2. (Note
that this requires that you come to the
class on the bonus due date.)

Chap. 1 Chap. 4 Chap. 5 Chap. 2 Elementary matrices Chap 6 of lecture notes summarizing what we will cover in each section provided by Professor John Quigg.

We will cover most of
Chapters 1 through 6, except 3, of the
textbook mentioned
above. Homework assignments, the
contents and
schedule of quizzes and exams are posted on
the assignment and Exam/Quiz
Schedule. Some
of homework will be assigned using
WeBWork. Please write
your homework **neatly
and legibly,** **PRINT** you name, and
**STAPLE** them
**BEFORE** class.
Most of the quizzes will be similar to
homework questions and the examples shown in
class or covered in the text. There will be
**AT LEAST** a quiz
every other week.
Some of the quizzes might be administered in
the Math Testing Center in PSA 21, and
some of them in class. When a quiz is held
in the testing center, you can take
the quiz anytime between 8:00am -- 6:30pm on
Tuesday and Wednesday. Please bring
your **ASU SUN card** to the testing
center.
The coverage on the final exam is the entire
course, although the material covered after
the preceding test has higher priority for
inclusion in the final exam.

Once exams/quizzes have been distributed, any use or handling of telephones is prohibited until you turn in your exam/quiz.

Exam 1: in class Feb. 8/9; Exam 2: in class March 8/9 Exam 3: in class Apr. 12/13 Final Exam: May 4 (TT class) 12:20-2:10, May 5 (MW class)

Final grades for this course will be
assigned according to the following
scheme:

75 points for average of
homework (with the lowest one including
excused ones dropped) 75 points for average of
quizzes (with the lowest one including
excused ones dropped) 100 points
for each of the three
midterms 150 points for the final exam

564-600pts="A plus", 540-563.99pts="A (excellent)", 528-539.99pts="A minus", 504-527.99pts="B plus", 480-503.99pts="B (very good)", 462-479.5pts="B minus", 438-461.99pts="C plus", 408-437.99pts="C (good)", 330-407.99pts="D (marginal)", below 330="F (insufficient)"

A grade of incomplete will be awarded only in the event that a documented emergency or illness prevents a student who is doing acceptable work from completing a small percentage of the course requirements. The guidelines in the current general ASU catalog regarding a grade of incomplete will be strictly followed.

Make-up midterm exams will be given at the
instructor's discretion and only in the case
of a **VERIFIED** medical or other
emergency, a conflicting
university-sanctioned activity, or a religious
holiday. When it is possible, the instructor
must be notified **before** the exam is
missed; if impossible, **the earliest
time you can**, failing to do
so will result a 0 for the missed exam.
**Adequate documentation must be
provided.**
Students participating in university-sanctioned
activities need to identify themselves
**prior** to
missing class and provide the instructor
with a copy of their travel schedule before
arrangements will be made to make up missed
work. **Nonrefundable
airplane tickets, family reunions, wedding
plans** etc.
are **NOT** valid excuses for missing
exams.

**NO make-up quiz will be given.** A
missed quiz will be excused **only
with adequate documentations**. When
a quiz is given in the testing center, the
missed quiz will only be excused
when you have documentation verifying
that you could
take the quiz **neither on Tuesday nor
on Wednesday**.

Exceptions to the final exam schedule and requests for make-up finals cannot be granted by the instructor. Please refer to the Department of Mathematics final exam policy for details.

**No late homework will be accepted**
except the following situation. If a
homework is due on a religious holiday,
**AND**, you make an arrangement with the
instructor **BEFORE**
the due date specified in
the assignment and the Exam/Quiz Schedule,
then the due date is extended to 5pm of
**the very next non-religious business
day (NOT next class).**
You are encouraged to do your homework as
soon as possible. Not only you will follow the
progress of the classes more, but also you
can avoid being unable to complete your
homework because of some last minute
emergency.
