IV. EXAM DATES, GRADING POLICY AND ATTENDANCE
Exam Dates
Midterm Exam : 23 November 2009, Monday (week 9)
Lab Final Exam : 07 January 2010, Thursday (week 15)
Final Exams
: January 11-24, Monday - Sunday, 2010
Grading Policy
Homework: 10 %, Quiz: 15%, Laboratory: 20%, Midterm Exam: 25 %, Final Exam: 30 %
Attendance (Clause 17 of the Undergraduate Regulation)
Classroom attendance is mandatory. Students, who are absent over 30% of the class time and 20% of the lab time,
automatically fail the course. Repeating students are exempt from attendance for a theoretical course only if the
attendance is fulfilled at least once for that course before.
Honor Code: All work done on the exams will be done on your own and pledged. Students may discuss homework
concepts and approaches, but the work will be done by the individual. Group or copied solutions are not permitted.
Homework is considered pledged simply by its receipt.
Late Work and Examinations: Normally, homework is due one week from the assigned date, unless otherwise
indicated or previous arrangements are made. Late homework will be accepted due to sickness only. Students who
know that they are going to miss class and/or lab session should make arrangements in advance.
A student who has not attended three lab sessions without an excuse, and therefore had his/her lab reports not accepted
will be treated as failed in the course.
Only selected homework problems may be graded from the set turned in. The others will be checked for completion.
Exams will be closed notes, open book and in-class.
