Plagiarism policy: You are obviously free to discuss among yourselves to help one another understand the concepts of the course. However, all assignments that are to be submitted are to be worked out individually and not in groups. If you have collaborated, you must reveal it during your submission. If N of you have collaborated, your total for that assignment will be divided by N. On the other hand, if you collaborate and do not reveal, you (regardless of the fact that you are the generator or recipient of the help) will be subject to disciplinary action as deemed fit by the instructor. Collaboration during exams will lead to strict disciplinary actions as deemed fit by the instructor.
