- Assignments: 20% of the total credit.
- Midterm Exam: 20% of the total credit.
- Surprise Tests/Quizzes: 20% of the total credit
- Final Exam: 40% of the total credit.
- There will be a total of 6 sets of homework assignments each
carrying a total of 20 points. 5 best assignment scores
will be taken for the final grading.
- The assignments will be given in class on every alternate Tuesday,
starting from January 12, 2010. Each assignment will be due in class on
the Thursday of the following week. For
example the first assignment is due on January 21, 2010.
- Each assignment will cover the course material done in class in the
previous week as well as in what will be done in class in that week. For example,
the first assignment which will be given on Tuesday, January 12, 2010 will
cover materials from lectures given in the week of January 4-8, 2010 and week of
January 11-15, 2010.
- Late submission of an assignment will not be accepted. If you
can not submit an assignment on time, don't worry about it, and try to do
well in the others. It will not count in your final grade since you
have few extra assignments anyway.
- Graded assignments will be returned in the class on Tuesday of week following their
submission. For example, the first assignment which is due on Thursday, January 21, 2010
will be returned after grading on Tuesday, January 26, 2010.

- There will be two to four
quizzes as surprised tests given in the
class. This means there shall be no pre-scheduling. A quiz will cover
materials done in the lectures given in the weeks prior to it.
- There will be NO supplementary quiz given for any student who
may miss a quiz for whatsoever reason. If you miss one then do not worry
try doing well in the other.
