COURSE GRADING:
The course grade will be based upon three mid-term exams, homework, quizzes,
and a comprehensive final exam. Grades will be based not only on technical
content but also on presenting your homework and lab reports in a well
organized, neat, clear, professional manner using standard technical terms
and symbols.
Exam 1 |
100 points |
@ approx. the 5th week |
Exam 2 |
100 |
@ approx. the 9th week |
Exam 3 |
100 |
@ approx. the 13th week |
Final Exam |
150 |
during finals week |
Homework |
100 |
|
Quizzes |
50 |
10 points each, only your best five scores count |
Total |
600 |
|
Final grades will be determined by the following percentages:
A = 90+, B = 80-89, C = 70-79, D = 60-69,
F = below 60
At the instructor's discretion, grading thresholds may be relaxed slightly.
Assignments are not accepted late. No makeup exams will be given
except by prior arrangement in exceptional, unavoidable, emergency situations.
Please contact me immediately if such a situation arises.
QUIZZES:
During at least 6 regular class periods throughout the semester, a short
quiz will be given. These quizzes are worth 10 points each, but only your
5 highest quiz scores will count toward your final grade. The remainder
will be dropped. Quizzes will not be announced in advance. Also, they
may occur anytime during the class period: beginning, middle, or end.
If you are not present when a quiz is given, you will receive a zero for
that quiz. No make-up quizzes will be allowed under any circumstances.
Suggested strategy: keep current and be ready.
ACADEMIC DISHONESTY:
Incidents of cheating or plagiarism are treated quite seriously. The NAU
policy on academic dishonesty in Appendix G of the 1998-2000 Student Handbook
will apply.
