Quizzes, mid semester and comprehensive exams

• Two quizzes will be conducted; one (quiz #1) before and another (quiz #2) after the minor exam. Exact date, time and place will be notified later.
• Mid semester and comprehensive exams will be scheduled based on the institute timetable.

Homework

• Homework will be assigned almost every week. These will not be graded. Hence, submission is not necessary.
• Students are strongly encouraged to try the homework problems.

Make-up policy

• If the student is unable to appear for the Regular Test/Examination due to genuine exigencies, the student must refer to the procedure for applying for Make-up Test/Examination. No make up for the assignments.
• Academic honesty and integrity are to be maintained by all the students throughout the semester and no type of academic dishonesty is acceptable.
