Homeworks, Pop Quizes and Examinations

PLEASE NOTE: Copying posted solutions in web will be counted as CHEATING in homeworks and Exams.

There are 5 homeworks given in Elearning.

Some "Pop Quize" may be given in class WITHOUT ANNOUNCEMENT.
Please note that there is no make-up for any quiz.
When you take quiz, please follow Rules for taking quiz

There are two exams, the midterm exam and the final exam. Their schedules will be informed in Elearning. Each exam is divided into two parts, take-home and in class.
All examinations are in class (close book and close notes).

Grade: Totally, 25 points for all homeworks, 15 points for Pop Quizes,
60 points for two exams. Each exam has 30 points.
Grades will be assigned according to the total number of received points:
A >= 85 > B >= 70 > B- >= 60 > C >= 50.

Letter from the Head of CS Department

"I want to welcome you to the Spring 2018 semester and wish you a very happy 2018. May you all make a 4.0 this semester. However, to reach that 4.0 you have to make sure that you attend all your classes. So let me take this opportunity to remind you that the CS Department observes rules for attendance that are strictly enforced: 3 consecutive absences result in a 1 letter downgrade and 4 consecutive absences result in an F. It is especially important that you do not miss classes at the beginning of the semester."
