It is the student’s responsibility to gather information about the assignments and covered topics during the Lecture Notes missed. Regular class attendance is mandatory. Points will be taken off for missing classes. Without 70% of attendance, sitting for final exam is NOT allowed. According to IUB policy students must enter the classroom within the first 10 minutes to get the attendance. 2. The date and syllabus of quiz, midterm and final exam is already given here, however, announcements will be given ahead of time. There is NO provision for make-up exams. 3. The reading materials for each class will be available to the online platform prior to that class so that student may have a cursory look into the materials. 4. Students will be notified in due time for class cancelation, extra class, make-up class and tutorial class. 5. Class participation is vital for better understanding of technological issues. Students are invited to class discussion and raise questions. 6. Students should take tutorials with the instructor during the office hours. Other than the office hours, prior appointment is required. 7. Students must obey the IUB code of conduct and ethical guidelines available in the IUB website through Greenbook. Students must read this green book before starting the class.
